Stanley No. 4: how to buy, what to check, how to document

The third and final instalment in the series. Dating Types 1–20 is in the first part; the variant overview is in the second. This one covers what comes after identification: how to recognise a good example, what to pay for it, how to avoid a harlequin — and how to document what you find so that the photographs actually tell you something.

Rarity — a working scale

The following is an authorial synthesis (production length, frequency in sales, price premium). It is not a Stanley factory classification.

Very scarce — collector market: Bailey Types 1–4, early Bed Rock Types 1–3, unusual transitional forms. Few public sales, prices high and spread wide. Buy only with detailed photographs of all key areas.

Scarce: Bailey Type 5 (first lateral), Bed Rock 604/604C across the board, No. A4 and S4.

Less common: Bailey Types 6–10, early Canadian examples, later Bed Rocks (Types 8–12), OH-4.

Common but quality: Bailey Types 11–16. The best quality-to-availability ratio — fully developed frog adjustment, pre-war machining, rosewood.

Very common: Bailey Types 17–21, most English No. 4s, post-war user examples. Cheap, functional, less collectible.

Market values — reference table

Prices reflect the 2025–2026 online market, a typical band for eBay and specialist dealers. European auctions tend to be softer. Verify at publication.

What raises value: low type number, rosewood (vs. hardwood), surviving japanning, original iron and cap, uncracked handles, condition of the sole and frog.

Authenticity — the three-zone method

The main risk with the Stanley No. 4 is not fakes but harlequins — body from one era, frog from another, a later lever cap, a non-matching iron. Check that the three zones are internally consistent:

Zone 1 — body + frog seat
Patent dates (or their absence), position of BAILEY and model-number castings, ribs at toe and heel, presence and height of the ring under the knob, overall casting style.

Zone 2 — frog + lateral lever
The lever type must match the body's dating. A kidney-hole lever cap on a Type 11 body = replaced part or wrong identification. A Y-seat on a body from the Type 14 era = error.

Zone 3 — lever cap + iron + cap iron
Hole shape (keyhole vs. kidney), embossed STANLEY, logo on the iron (Sweetheart, V-logo, B&G…), cap-iron compatibility. A modern iron without period patina on an early body = red flag.

What matters is the agreement of patina and wear across the whole tool — not the dogma that every part must fall into a single table row. Stanley itself assembled transitional combinations of parts, so an original hybrid of adjacent types is real and perfectly fine.

What lowers collectible value

• A drilled hanging hole
• Toe and heel ground square ("de-beaded")
• Welded or brazed cracks around the mouth
• Unprofessional repainting or refinishing
• Over-milled or heavily lapped sole
• Undisclosed reproduction handles
• Late or English replacement parts on an early American body

Typical wear

Cracks in the sides and around the mouth, chipped mouth, broken top of frog at the lateral, cracked knob base, broken horn on the tote, deformed adjuster wheel, cracked or delaminated iron, pitting in the sole ahead of the mouth.

Worst for function: cracked body, broken frog, faulty lever cap, deep pitting just forward of the mouth. Damaging for collectors even when the tool works: cosmetic interventions.

Buying recommendations

For the woodworker (you want to use it)

Best quality-to-price: Types 11–16, or a good Type 18–19 or a quality British post-war example before the late plastic era. Buy condition and adjustability, not rarity.

Five things to check in person:

1. Body free of cracks at the mouth and in the sides.
2. Top of the frog at the lateral intact, not broken off.
3. Sole without deep pitting just forward of the mouth, no twist.
4. The horn on the tote may be repaired — but solidly and honestly.
5. The cap iron must seat tightly against the iron; otherwise tear-out is a constant fight.

For the collector (you want typological integrity)

Priority: a typologically correct early example without cracks → a nice Sweetheart with a period iron and the right lever cap → only then the exotics (A4, S4, early Bed Rocks).

On scarce examples (Types 1–4, A4, Bed Rock Types 1–5): do not buy without detailed photographs of all three zones. Request: the area behind the frog, the frog seat, the lateral lever, the lever cap front and back, the iron, the tote and the knob. Without those photographs you are buying blind.

The one safe recommendation

An uncracked, complete, American Type 11–15, or a good British post-war example with wooden handles. Accessible, functional, dateable, and still honest to look at.

Restoration — what to do and what to avoid

Standard approach: disassemble → de-rust (Evapo-Rust, citric acid, electrolysis) → check the frog seat → lap the sole → sharpen the iron (primary bevel + micro-bevel) → tune the cap iron → careful handle repair → test shaving.

Avoid: grinding the sole beyond what is strictly necessary; removing original japanning; over-polishing the brass; replacing original handles unnecessarily.

Curiosity: the Ready Edge Blade system (late 1920s / early 1930s) — a screw-on replaceable edge. A collector's oddity; for a user, usually a reason to buy a standard replacement iron instead.

Photographic documentation

Photograph as an identification set, not an aesthetic hero shoot. A well-photographed plane can be typed from three to five technical images; a poorly photographed one cannot be typed from twenty attractive ones.

Minimum set for publication

For Bed Rock: additionally photograph body and frog separately — the full frog seat is the whole point.
