So I don't know it is legit. The gun looks like there is wear but still a great novelty item.
The Santa Fe G3
HK G 3 7/62 : Rifles
The finish seems really worn, and it is a 7/62 (not 3/62--- big difference)!!!
Hopefully when he sells he'll have enough money for a better camera. I'll never understand why some people with high-dollar items can't seem to take a decent pic.
