I apologize. I gave you the wrong info on the model with the hammer. I was looking at several guns and got two mixed up. Your gun with the hammer is a .38 Double Action 3rd Model.
These were manufactured 1884-1895 Serial number range from 119001-322700. 3.25" Barrel and it does have correct grips. Sorry for the mix up. It really is in great shape to be well over 100 years old. Amazing they made over 200,000 of this model alone.
No need to apologize at all. I realize that you are taking a lot of you personal time doing this for the community and I really appreciate it. Thank you for taking the time to clarify. It really helps me a lot.
