I was following this thread intermittently. I would say that there's a chance the seller, when he discovered the truth, enlisted a "buddy" to "buy" the gun and then feign satisfaction with the purchase. No way of knowing, of course, and my intent is not to badmouth either party, but I know this type of thing goes on behind the scenes, not just with guns. Regardless of what really transpired, hopefully nobody actually got "stuck" with the psuedo-Rigby.
