I re-examined the pictured parts.
The top op slide has a hard to read P/N with the "w" on the bottom of the well and came off an IBM M1that I bought thru the DCM for $20.
The top TG Assy has the letter "A" stamped just forward of the TG behind the assembly hole for the safety/mag catch assy spring
The bottom TG Assy has a "U." stamped in the well and is laminated (?). It also has two grooves in the back of the well. This came off the same DCM M1 s above
The bottom Op slide has a P/N on the bottom followed by "SA"
Thanks for your response.
