NOTE: This type discussion, along with the foregoing material, is based on personal examination of numerous Bed Rock specimens since 1973. Frog & bed machined & mated 100%; inclined frog seat. Keen Kutter Bed Rocks had plain lever caps and Winchester Bed Rocks had Winchester marked lever caps.Many specimens have been seen, but there is always the potential for finding a new type or an anomaly.
Lateral adjustment lever with patent dates 10-21-84 &7-24-88. The planes were identical to the original Stanleys, except for the markings on the beds, (W.., K..), Keen Kutter and Winchester trademarks on the blades and frogs with twisted lateral levers.
"S" casting mark on bed (raised dot on some specimens). Frogs with "B" casting marks. During the 1920's, Stanley manufactured Type 4 Bed Rock Planes, for Keen Kutter and Winchester.
The format used for the type discussions and trademark designations generally follows other published studies. This is the Type Study part of a larger paper of 8 pages that also discusses the history, development and characteristics of this, the best plane ever made. See Beds marked with Bailey model numbers, No.2 to 8.
All sizes in production including those with corrugated bottoms.
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.
