Getting back to a discussion:
I have found there are three(3) variants of the C.S. Shattuck, Hammerless double. All references I have found thus far only mentions two. So gentlemen which type do you have in you cabinet and what range are the ser#'s?
My three are #823X, #768X, and #321X.
823X and 768X utilize a cross pin through the frame as a pivot/retainer for the barrel catch. #321X uses a quarter sized plate held to the bottom of the frame with two screws.
The third type (ser# not available) has a smaller plate with only one screw. There are other subtle differences between these models also.
Did R. Torkelson work for C.S. Shattuck?
If anyone has more info to add or ser# ranges per type/model please list it.
