The top one has a brass frame,stamped 36 behind the hammer on the brass.
Has the Colt address on top of barrel, but only US on left side of frame.
All matching numbers, that is all I have at this time.
The bottom one has a crack on one of the cylinders,new one in the mail.
decent rifling,nicer wood than 36cal model.
I am still researching them at this time.
