I came across a Beretta M1935. Its in very good shape. Has the original leather holster and 2 mags with it. Im looking to find the year the gun was made by the serial number. All I have found out so far is that it was made between 1935 to 1959. I would like to narrow it down more. Does anyone know of a website that has the information to where I can find more of the exact year? Thanks
