Just received a model 36 purchased from a Forum member. Gun is great and all I expected. I believe serial # dates to '61 but would like the experts to verify (269171). Came with box and some paperwork. If anyone has original paper work for a 36 of this vintage I am in the market Included with the gun was the original sales receipt for $42 ??? Now have the nickel, blue and stainless versions of the Chiefs Special.
