Stanley bench plane dating page lewis copeland dating
When dating planes, especially bench planes, it is usual to concentrate on the main parts - bodies, frogs and lever caps.Other smaller parts, including cutters, are user replaceable and could distort the dating process if not original to the tool. The listing does not include the No.605-1/4 (see note at Type 7), but does show the No.602-C as being available, which contradicts the assumed 1918 end of production for that model. Allow time for the page to download, as the image is large, in order to maintain some kind of readable quality. I recently obtained an original copy of a 1923 Stanley promotional pamphlet which illustrates and describes the Bed Rock Planes in production at that time.Even then, some overlap in date ranges must be allowed for.
These periods are based on there being at least two common factors in the main parts of the planes in each period, including cutters.
It has also been noted that some very early 2-inch lever caps are slightly shorter (by 2mm) than later ones and have an indistinct flat about 7 mm wide on the inside lower edge, similar to that found on the 2-3/8 inch size. K., most RW planes have been found to comprise a mixture of original Steel Nut and Record specified parts.
In this study, these planes are referred to as ‘changeover’ planes and such examples will date to c.1961/62.
There may be some overlap and change as more examples and data is collected., small 5/32 inch (4 mm.) mark and single pane lower face frame, c.1954/55; 7/32 inch (5.5 mm.) mark and two lower face frames, c.1955/57 and Foundry mark "Q" in upper left hand face frame and right hand frog orifice lower than the left, c.1957/61.
Early and mid dated planes were packed in L1 boxes and later planes in L2 boxes (see packaging below).
