Stanley bench plane type study
Stanley Type 20 (1962–1967)
Kidney-shaped hole in the lever cap. Blue paint rather than japanning. Often plastic handles by the end of the run.
- 1962–1967
- high confidence
Fastest way to spot one
- Kidney-shaped hole in the lever cap
- Blue paint rather than japanning
- Often plastic handles by the end of the run
Features in detail
| Lever cap | The hole becomes kidney-shaped. This is the most recognisable single feature in the study and the conventional end of the collectable era. high |
|---|---|
| Finish | Painted rather than japanned. high |
| Handles | Plastic handles appear in this period and after. medium |
Notes
Collector interest falls off a cliff here, which makes a Type 20 the cheapest way to own a working Stanley. It is a perfectly good plane; it is simply not a collectable one.
Before you trust this
Type dates are approximate and adjacent types overlap. Stanley emptied parts bins before opening new ones, so a plane can legitimately carry features from two types at once. Date the body casting, treat the iron and hardware separately, and expect a window rather than a year.

Models this type applies to
-
Stanley No. 3 Smoothing Plane
A smoother one size down from the No. 4, and the size most people find comfortable once they have used both.
-
Stanley No. 4 Smoothing Plane
The most-produced bench plane in history and the default smoother in every workshop that has one.
-
Stanley No. 4-1/2 Smoothing Plane
A wide, heavy smoother.
-
Stanley No. 5 Jack Plane
The jack plane - the jack of all trades, and the plane most likely to be in a box at an estate sale.
-
Stanley No. 5-1/4 Junior Jack Plane
A narrow, short jack sold heavily into school manual-training programmes.
-
Stanley No. 5-1/2 Jack Plane
A wide, heavy jack.
-
Stanley No. 6 Fore Plane
The fore plane sits between the jack and the jointer.
-
Stanley No. 7 Jointer Plane
The standard jointer, and the plane that makes hand-cut edge joints possible.
-
Stanley No. 40 Scrub Plane
A dedicated roughing plane: narrow, thick, heavily cambered iron and a wide open mouth, made to take deep bites across the grain and reduce a board fast.
