Hello all,
I recently acquired a 37mm projectile from an auction that had only a picture straight on, and the typical vague measurements. I thought then it might be a US M94 sub-cal for the 1.457 gun, and the measurements are pretty close to that, but there are 2 differences: the M94 that I’m familiar with has a base plug, whereas this has a tracer hole. Also, the M94 typically has text engraved above the band in the projectile body, but this has no markings whatsoever. Comparing it to an M74 rules that out as well.
Can anyone help ID?
Measurements are as follows, and pictures included.
OAL 107.55mm
36.53mm base dia.
18.25mm band seat width
35mm straight body before ogive starts
36.75mm body dia.
12.5mm wide tracer hole
4mm from base of projectile to crimp groove
Measurements taken with Brown and Sharpe digital caliper, NIST calibration verified 8/19
Thanks!
