Found this tool today while cleaning my shop. It says Sterling Petrel on one side and valve lifter on the other.
Is it a Model T era tool?
How would it be used and what for?
Sterling Petrel were boat engines
I found an ad for the engines in google books.
The ad said the motors came with a valve lifter and other special tools.
