There are no springs under the firing pins. Should there be?

The barrels are marked LC SMITH MAKER . SYRACUSE N.Y. on one and STUB TWIST BARRELS on the other.

There is one old gunsmith reasonably close that still may do color/case. I may take it up with him. It's going to be a real problem keeping these old guns up and running when so many of the old gunsmiths pass on.
