My dad just gave this to me and I have zero idea what this is.
All I know about it:
Looks a little like a stubby DM2 shape.
NO IRG. Totally flat. Angled slightly outward.
The axle seat is cracked so I can’t get it open Would really love some advice on that too.
Even though in the 2nd photo it looks like a DM2, again there’s no IRG.
(I haven’t posted something like this before so I thought that this thread would be pretty appropriate.)
