Thank you for such a quick reply. I apologize for giving poor information about the second revolver- It is for sure a Smith & Wesson, hammerless lemon squeezer type in 38 S&W caliber. It was hard for me to read the serial number and I mis-read it. The correct serial number, as best I can read it, is:157 089.

The three patent dates on the barrel are also very hard to read, but as best I can make them out, they are: Oct. 1883; Aug. 1885; and April 1889. Does this make more sense?
Other barrel markings indicate S&W, Springfield Mass. on the 4" barrel.

Thanks for any iformation you can give.
