This is not an original G.I. frame. As noted the engraving does not look right, but the big
"giveaway" is that the gap in the tang that engages the grip for the grip screw looks to be
about 1/2" wide whereas on original frames it is about 1/4".
Also missing are the machining marks left by the cutters that are used to machine the
frame. Original frames have swirl marks on the sides, and also on the top between the rails
that engage the receiver. The photos are not that clear and the lighting is poor, but it looks
like every surface of this frame is completely smooth with a flat sandblasted finish and no
machining marks of any kind.
OK, we all agree it's not AOC or Savage, but who made this frame? I have never seen
one like it. Making a trigger frame is a lot of work. Did somebody actually take it upon
themselves to make ONE frame? Yet not put them into production?
Phila Ordnance (me) made M1928A1 trigger frames 40 years ago. They were perfect
in every respect, but are marked with a keystone on the left front of the trigger guard and
so are easily recognized. I only made about 20 of them, which at the time I sold for $195.
A short time later Sarco offered Thompson complete part sets for $195. Nobody is going
to buy a trigger frame for $195 when you can get a complete parts set for $195 and the
project was instantly terminated.
