Here are three samples of Toledo manufactured Mosin cartridges: F. N. T. 1944 - F N T 45 - F N T 50.
The F. N. T. 1944 appears to have been loaded from salvaged cases. According to Molina-Orea, these cases were of spanish wartime manufacture and the original raised headstamp on the beveled part of the head has been obliterated.
All of them have GM bullets and brass cases, although the 1950 has a mock CWS finish.
I must have a better F. N. T. 1944 specimen somewhere. Will post the headstamp if I’m able to find it.
