I don't own any of these, but they and the Colt (and Pieper) copies are one of my favorite parts of the A.B. Zhuk book of line drawings of handguns.

There are tons of different variations on everything from side plates to cylinder latches.

A lot of them seem to have been .38 Long Colt rather than .38 Special, although supposedly a lot are bored straight through and will take Specials, although it's a bad idea to use them.
