Anyone know what this U.S. marked tool is?

[B.S.A. (ret.)]

Picked this little item up in a box 'o stuff at a yard sale a couple of years ago, and just ran across it while doing some clean up. At first, I thought that it might be a brake piston compression tool or maybe a battery terminal puller. No luck in Googling it so I throw myself at the mercy of the GJ experts. It is marked "ET-1700" & "U.S." under the number. Thanks.

Ok, so I was on the right track with my battery terminal remover guess. What threw me was the "U.S." marking under the tool number. Apparently a military contract item?

Or just made in the US.

Possibly, however everything that I've seen with a "U.S." marked on it was an "issue" item as in "Property of the U.S. Government". Generally, civilian items are marked "Made in the U.S.A." Being prior military, I was looking for someone who might have come across one of these in their service.
