Welcome to the forum. Assuming the serial number is 112148, you have a 32-20 Hand Ejector of 1905, 4th Change, these were made from 1915 to 1942. This gun has been re-blued, evidenced by the plum coloring of the cylinder, thus taking away the collector value. Who ever did the re-blue was correct in not blueing the hammer & trigger, as they show the original case hardening. The grips are from a later era, original would have Diamond Magna stocks. The numbers that you mentioned are assembly numbers used to keep parts together during the manufacturing process. Your gun looks to be in great shape and should be a good shooter. As to pricing I will leave that to others, who I am sure will be along shortly.
Again welcome and we hope you stick around, there are a lot of great people on this Forum that are willing to share a wealth of knowledge.
