I came across a Colt 9mm receiver set on armsunlimited.com.

It has their Vietnam Tiger Stripe camo and appears to have all the lower internals including the magazine block. I know Colt made a 6920 in the Vietnam Tiger Stripe, but I don't remember them selling a 9mm. Any idea what the story is behind these? I called and the lady I spoke with said that they came from Colt as pictured inside a manila envelope.
