The pictures below show an unusual KR Wilson Model A, B, and V8 Ford era service tool. This is the KRW BV-45 Step Feeler Gauge as shown on page 43 of the August 1932 Ford Service Bulletins.
This gauge has feelers for each of the important valve, ignition, and spark plug gaps. Many of the feelers are step-ground to high and low limits to function as "go" and "no-go" gauges.
This gauge was made by the L.S. Starrett Company for K.R. Wilson and was marked with the identification of both companies.
