Anybody Recognize this Dovetail Jig?

[James McKinley]

A friend was showing me his tool collection and he had this adjustable jig for marking dovetails. No manufacturer's mark on it. Does anyone recognize it? Thanks in advance.

Howdy James and welcome to the Creek. Those show up on ebay occasionally, not sure who made them.

Seem to think it was by Richard Kell.

This dovetail marker is seen in Robert Wearing's book "The Essential Woodworker".

An excellent book now republished by Lost Art Press.

Best wishes,
