M3 Holster.....Real or fake?????

I seriously looking at a M3 holster on Ebay. It really looks "to good to be true".
I appears to be unissued. I'm planning to bid on it tonight If its real. Wouldn't a 60 year old holster start to turn brown after so many years out in the air??? It dose show some virta gree(sp?) on the snaps. I really need some help here with this one.....

It looks good to me. It has all the characteristics I look for in a M3 and none of the tell-tale signs of a fake. I have a moderate collection of M3s and have learned about them by trial and error. While mint holsters like that one are rare, I have a couple that are nearly that nice.
