I got my letter on my greatgreat grandpas 32 hand eject it is a M-1 first issue cylinder latch on the top the S%W cataloge said that this was first issue then thay changed to the latch on the bottem the ser number is low 32xx the letter said it was shipped in 1899 i think that is odd that after a change like moving the cylnder latch from top to the bottem the frame would have not been used and shipped sooner or is this how S&W did things
