I’ve recently purchased a new 20x110RR Oerlikon round at a gunshow. The projectile is a solid gray color, which according to my references is of a HE/T type, on a brass case. However, I cannont find any info on the headstamp.
The date of manufacturing is 1942 (42 at twelve o’clock), but it has a “546” at 4 o’clock, and the letter “B” inside a diamond at the 8 o’clock. Can anyone help me with this information?
Thank you all for the help.
