Again post WW2 and not fired by Garand. It used the 30-06 cartridge while this one is .308 win/7,62x51 Nato.Manufacturer was German company named Manusaar, located in Saarbrucken I think. Probably doesn't exist any more...it's possible that the number code contains the year..probably 59. 57 is likely some batch code.
