M3 Holster... Real or fake???

Gentlemen,

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.....

Thanks for looking

Looks real enough to my eye, just extraordinarily well stored. Only you can decide if an M3, even in this shape, is worth where the bid is now.

Oh... and it's "verdigris"
