NOTE: This type discussion, along with the foregoing material, is based on personal examination of numerous Bed Rock specimens since 1973. Many specimens have been seen, but there is always the potential for finding a new type or an anomaly. The format used for the type discussions and trademark designations generally follows other published studies. Emphasized features are in BOLD ITALICS.
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. The complete paper may purchased for $3.00. See Tool Literature.

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.  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.  Click pamphlet cover to view entire publication.  Allow time for the page to download, as the image is large, in order to maintain some kind of readable quality.



During the 1920's, Stanley manufactured Type 4 Bed Rock Planes, for Keen Kutter and Winchester. 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. Keen Kutter Bed Rocks had plain lever caps and Winchester Bed Rocks had Winchester marked lever caps.



Bed Rocks that do not fit within the foregoing sequence and evolution of the series add interest to this and future studies.

TYPE 4Z. c.1910

- All characteristics of TYPE 4., except...
Beds marked with only slanted single digit numbers:"2" - "8", lightly milled space on some planes where the "K" or  "W" would have been for a Keen Kutter and Winchester.  Planes made for Keen Kutter and Winchester but later sold by Stanley in the general market.
No patent dates on the bed. Keen Kutter lever caps plain. Winchester lever caps marked Winchester. Twisted laterals on both makes. Blades marked with Keen Kutter & Winchester logos.
-Owner-modified planes represent random anomalies rather than factory created types-
•Later Bed Rock, Type 5 or later with round profile sides,  likely re-ground by owner.
•Various types with plain, un-marked lever caps;  likely owner replaced.

I would be interested in hearing about any other anomalies and/or variations that exist.
