So there is a 3 inch royal blue Python listed on Gunbroker. It says it is 100% condition and not a remake or a barrel swap. It has no box or papers. I called the seller and asked them if they had a factory letter. When they said they did not I asked them how they could authenticate it being an original 3 inch barrel. The answer. We are a gun shop and we can tell such things. Well I guess I need to go ahead and bid!
