A friend sent me these pics of an old revolver that belongs to his brother. I have researched it some but want some expert info if any is available here. The serial # is not visible and the pics he sent me are not the best. I have attached a couple of pics of the same type of revolver that I found online. He would like any info and pricing if possible. By looking at the pics he sent the condition seems poor. I have not seen this in person. He thinks it is a " MAS Model 1874 Chamelot-Delvigne 11mm Service Revolver". I agree it seems to be a variant of this style revolver but it is not the same. I also came up with some info about it possibly being a M 1880 variant. Any help would be appreciated, thanks CAB.
