The Store p438 Buttercup Hair Clip: A Vintage Brass Accessory Guide
When you hold a Store p438 Buttercup Hair Clip in your palm, the first thing you notice is the weight. It is not heavy, but it carries a satisfying density — a small, golden disc with five rounded petals radiating from a warm brass centre, each petal catching the light at a slightly different angle. The clip was produced in limited numbers during the late 1950s by a small London workshop that specialised in botanical motifs for the millinery trade. Unlike many mass-produced hair accessories of the era, the Buttercup clip was assembled by hand, with each petal individually shaped and soldered onto a spring-loaded barrette base. The result is an object that feels both delicate and sturdy — a piece of jewellery for the hair, designed to last.
The buttercup motif itself carries a quiet symbolism. In the language of flowers so beloved by Victorian and Edwardian Britons, the buttercup signified humility, neatness, and childlike joy. By the 1950s, this floral vocabulary had softened into a more general nostalgia for rural English life — a counterpoint to the rapid urbanisation and post-war rebuilding. Wearing a buttercup hair clip was a small, personal act of connection to hedgerows and meadows, even if your daily commute was on the Northern Line. The p438 model is distinguished by its unusually deep cupping of the petals, which creates a strong play of shadow and light, and by the fine cross-hatching engraved on the central brass button — a detail often worn smooth on later reproductions.
Identifying an Authentic Store p438 Buttercup Clip
Because the p438 was made in a single production run, genuine examples share a clear set of characteristics. First, the metal is a solid brass alloy with a light gold tone, not a bright yellow or a pinkish brass. Over decades, the surface develops a soft patina — a mellow sheen that cannot be convincingly faked with chemical ageing. Second, the spring mechanism is enclosed in a slim brass tube, not a flat metal plate. When you open the clip, you should hear a crisp, clean click, not a scraping or grinding sound. Third, the stamp on the inside of the barrette reads “Store — p438 — Buttercup — England” in a serif font, with the letters evenly spaced and slightly recessed. Any variation in the stamp — missing words, a sans-serif typeface, or a country name other than England — indicates a later copy or a different model altogether.
Collectors also look at the condition of the petals. The original p438 has five separate petals, each attached at a single solder point. Over time, one or two petals may become slightly loose, but they should not wobble independently. A clip with all five petals firmly attached and unbroken is rare and commands a higher price. The back of the clip should show a smooth, untextured brass surface, with no visible screw heads or rivets. The hinge is hidden inside the tube, which gives the clip a clean, streamlined silhouette when viewed from behind.
Materials and Craftsmanship
The workshop that produced the p438 specialised in lost-wax casting for small jewellery components, a technique that allows for intricate detail without the cost of hand-engraving each piece. For the Buttercup clip, the master pattern was carved in wax by a craftsman named Arthur Pendelton, whose initials AP appear in microscopic letters on the underside of the central button — a detail most owners never discover. After casting, each clip was hand-filed to remove casting seams, then polished with a rotating mop and a fine pumice compound. The final finish was achieved with a light application of jeweller’s rouge, which gives the brass its characteristic warm glow without making it look lacquered or plastic.
The spring mechanism was sourced from a specialist manufacturer in Birmingham’s Jewellery Quarter, a family firm that had supplied watchmakers since the 1830s. The steel used in the spring is a high-carbon alloy that resists fatigue, meaning the clip retains its tension even after sixty years of occasional use. This is one reason why the p438 remains functional today — a well-maintained clip will still hold firmly in fine or medium hair without slipping.
Styling the Buttercup Clip in a Modern Wardrobe
The p438 Buttercup clip works best as a single statement piece. Its modest size — about the diameter of a two-pence coin — means it does not overwhelm the hair, but its sculptural quality draws the eye. For a daytime look, slide it into a low side ponytail or use it to secure a loose French twist. The warm gold complements navy, cream, forest green, and dusty rose — colours that appear frequently in British heritage brands like Barbour, Toast, and Liberty. For evening, try wearing it as a hair brooch on a softly waved bob, positioned just above the ear. The buttercup motif reads as romantic without being girlish, and it pairs especially well with textured fabrics like tweed, corduroy, and brushed cotton.
If you own more than one p438, they can be clustered in a small group of three, staggered along the hairline, for a more elaborate effect. This styling trick was popular in the early 1960s and is seeing a revival among vintage-loving fashion editors in London. Just be careful not to overcrowd the clip — the beauty of the design lies in its negative space, the way each petal leaves a tiny shadow on the hair beneath.
Care and Storage for Long Life
Brass naturally tarnishes when exposed to air, moisture, and the oils in hair and skin. To keep your p438 Buttercup clip looking its best, wipe it gently with a soft, dry cloth after each wear. Avoid using chemical jewellery cleaners, which can strip the patina and dull the engraved details. If the clip develops a light tarnish, a very small dab of Brasso on a cotton bud, applied only to the raised surfaces and immediately buffed off, will restore the shine without damaging the recessed areas. Never soak the clip — water can seep into the spring mechanism and cause rust.
Store the clip in a dry, dark place, ideally in a fabric-lined jewellery box or a small cotton pouch. Do not keep it in a plastic bag, as trapped moisture accelerates tarnishing. If you have several vintage hair accessories, separate them with acid-free tissue paper to prevent metal-on-metal scratching. The p438 is sturdy, but its solder joints are the weakest point — avoid dropping it onto hard floors, and never force the clip open wider than its natural stop.
Where to Find One and What to Pay
Genuine Store p438 Buttercup clips appear at vintage fairs, estate sales, and online marketplaces with varying frequency. In the United Kingdom, you might spot one at Portobello Road Market on a Saturday, buried in a tray of mixed costume jewellery, priced at £20–£40. Online, expect to pay between £45 and £75 for a clip in good condition with all five petals intact. Clips with the original box — a small cream cardboard box with a green “Store — London” label — are rare and can fetch over £100. Be wary of listings that use the word “Buttercup” without the model number p438; other makers produced similar floral clips, but only the Store workshop used that exact designation.
For collectors who enjoy the thrill of the search, the p438 is a rewarding target. It is not so rare that it feels impossible to find, but it is uncommon enough that each discovery feels like a small victory. And because the design is both timeless and distinctly mid-century, it fits seamlessly into a wardrobe built around vintage and contemporary pieces alike.
A Note on the Buttercup’s Place in British Accessory History
The p438 was produced during a golden period for British hair accessories, when small workshops in London and Birmingham were experimenting with sculptural forms inspired by nature, architecture, and the abstract shapes of the Festival of Britain. The Buttercup clip belongs to a family of floral barrettes that includes the Sweet Diamante Barrette, which uses a similar petal arrangement but adds crystal accents for a more formal look. Together, these pieces document a moment when hair accessories were not mere fasteners but wearable sculptures — objects that rewarded close looking and brought a touch of the garden into everyday life.
For a first-time collector, the p438 is a solid choice — it’s not overly expensive, and the authenticity markers are clear enough to learn with. Start by examining the central button for Arthur Pendelton’s tiny initials; that single detail connects you to the hands of the craftsman who carved the master pattern. That, more than anything, is what makes the clip worth seeking out.
