Help with tool identification

[DeutscheMech]

So, I bought this tool from a distributor who got it from a retiring GM tech. Neither the distributor nor I have any idea what it is, but it is brass. I'm trying to harness the power of the internet to identify it. What did I buy?

All markings appear to be worn off, but here's a profile view

I can't tell how long it is but it looks as though it may be a temporary brace when removing a drive train component or motor mount . just a guess !

It measures 8 5/8" from tip to tip. Wide end is 2 1/8" x 2 1/4". Narrow end is 1 1/8" x 1 1/4".

Whenever I see brass or bronze like that, I think non sparking. Think if it were a temporary brace or bracket, they would have cast it in iron. All I got.
