I have a chance to buy 2 model 29s. Both are 29-2s IIRC. The first one is a 29-2, blued, 4in, NIB - presentation case that is. It doesn't really even have a turn line. The other one, is a 8 3/8 gun in nickel thats also NIB - presentation case. Both are fired. I'm thinking that the seller will ask more for one than the other so I'm wondering which one should I gravitate towards? I think the 4in gun is the more collectible/more in demand 29 but I don't see many long barrel nickel 29s either. What say you?
