A pipefitters tool to mark a cut line around a pipe. The v portion is held tight to the pipe which then keeps it parallel and the end of the pantograph style arm has a small clamp for a soapstone,you then set the desired angle you require and then carefully mark a line around the pipe by moving the arms.

I didn't see the tag saying .25 when I first responded,but, if you spent $25 you got a deal, if you payed 25 cents then you stole it congrats. Jim

That was quick!
 OK the story

 One time at the mine we were tired of slogging through a swap every winter.
Since it was not totally mandatory to clear it up the company wasn't giving us anything. 
It became kind of a crew project to fix it.

 We all decided if we had drainage it wouldn't hold water and eventually dry out.  We had pipe to make a drain out of in the boneyard, but we didn't have any fittings. We needed a 45 degree bend.
 Well Mcmaster had these tools, (big ones, it was 18" pipe)  but they were spendy.
  Like in $700 bucks spendy! 
But they gave me a tiny picture in the catalog.

 So I took a piece of channel iron and some flat bar stock, screws and washers etc and made one.
 It wasn't so elegant, but it worked! I was able to mark the 2 pieces of pipe, torch them and weld them up.
 
  It all worked in the end, and the swamp was gratefully drained.

 Later when I found this small one I knew exactly what it was,
 and was delighted.
  yours Scott

Nice find - sure beats the old fragile paper templates I have in a file folder.
