Re: Some original trainer pics
It is thought that the MC 58/65's were M14 trainers as they were developed in 1958. There was a fullauto prototype made around that time. If you look at my M65 pic, you will see a longer almost curved mag. Some say this mag was for the fullauto version. It is two standard mags with a professional looking silver brazed plates to hold them together.
I have three 513T US property's one with the "Military Finish and the other two are blued. Also have the 52 C&D target rifles. I'll post more of the other trainers in my collection later.
