Odd 1920 Navy...?

[Pete Ebbink]

Have folks seen such a chamber marking before...?

I was thinking the "period" should be a "comma" to be corect for the German numerical system.

The stamping on the magazine base looks odd as well...maybe too new and not matching the "germany" stamping...?

Regards,

Pete...
