Here is a picture of the shotshell cartridge with cooper base and alluminium body. It’s looks factory loaded.
Please, help me to find answers on following questions:
- Who was a manufacturer of this cartridge?
- When this cartridge was made? Before or after WWII?
- Who was a manufacturer of the primer with headstamp “MO”?
- If primer manufacturer is known, did it also produced .22LR ammo with indented headstamp “MO” (last picture, right)?
Thanks for any information
