Picked this up at a auction.
No idea what year it is. It is a compression tester. It records the pressure on little cards using a arm with a piece of tiny crayon attached. The cards have a pressure scale printed on them.. and are removable to show the customer or other. Made by MotoMeter.. which I think also made radiator temperature gauge caps in the teens and 20's
Remarkably they still make recording gauges...

Well I'll be damned!
Proper quality kit! When I did one year of Auto repair class in the early 80s, we had those.

I looked around further on that site and see they still have the recording chart paper. Probably for yours!

Proper German engineering. How things should be done 😁
