This is a float level gauge for setting the float level for a ETW1 carburetor. These are what is used in Dodge M-37 army trucks from the 50s & 60s. This is also known as GAGE 41-G-187 And yes, they spelt gauge as gage in the manual.
I put a picture of an M37 army truck in here for those of you that were wondering.
