I got it from the machinist's estate I was clearing out a few months ago.

It is hardened and ground. Cross drilled for setscrews. The angles are
around 65 degrees. The holes are 7/16"dia.
The name stamped on it is the name of the owner (and presumably the
maker) and it gives the impression of the sort of tool you would make
during your apprenticeship.

It is very nicely made, but I'll be darned if I can figure out what it's
for.

It looks like it could be a test peice for some advanced metal working
class. Some "alphabet soup" organization has a bunch of prints of
peices like that to "certify" machinists. The shop teacher has a few
of the advanced students starting on these this year.

Could be, but why bother to harden it. Also, it wasn't in a cigar box on the
shelf, it was in a cabinet with vee blocks and angle blocks and other tools
that would see regular usage. This guy finished his apprenticeship before
WWII.
I can't imagine he just liked to look at it for all those years.

I also thought it might be used with drill bushings. Either for cross
drilling rods or drilling angled holes, but the angles are kind of oddball.
