I have this headstamp on a .45" Peabody-Martini cartridge and I believe that it’s a military loading made for Romania. It’s designated the .45 m/79 Romanian Carbine and it has a caselength of 40mm.
Despite the rather misleading headstamp all the references that I’ve managed to find suggest that this cartridge was made for Romania by the British company, Kynoch. The same headstamp is also found on the .45" Romanian Peabody with it’s 49mm caselength.
The only variation in the headstamps is the number appearing at 6 o’clock so I would suggest that this indicates either a month or lot number.
The ‘79’ is found on all of these headstamps so I am assuming this is the model number - m/79.
The ‘81’ is also constant and is probably the year of manufacture.
But my question is why the ‘M’? If these are made by Kynoch why isn’t there the usual ‘K’?
Does anybody have any packaging for these cartridges, in either calibre, that might clarify their manufacturer?
It’s been suggested to me that the ‘M’ could possibly be for Ludwig Mandel of Austria.
