- 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.

- END OF PRODUCTION FOR BED ROCK PLANES.
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.
BED ROCK PLANES MADE FOR KEEN KUTTER & WINCHESTER
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.
ANOMALIES AND OTHER PUZZLES
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
AFTER MARKET "TYPES"
-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.
- - 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.
