Gents, After being here for a while, today I will make my first attempt at posting pics. I am hopeful that someone can help identify, if this is a gunsmith job (and possible who?) or a somewhat skilled job by a previous owner. Background - this is a S&W model 35 front sight, I bought the revolver off of GB a few months ago from a seller in Louisiana. Always wanted one for a shooter, more than a collectors piece and this one was perfect for my needs. Original listing pics showed a front sight covered with red fingernail polish. As the back of the sight looked a bit "rounded" for lack of a better term, with the polish, I went at it with a plastic pick and a chunk of polish came off revealing this small copper tab, which appears to have been silver soldered to the rear flat of the target front sight. I previously posted, asking about the use of acetone to remove polish, so I left it as is, until I could get back to it. Here's an after the removal of "chunk/blob of polish" before pic Attachment 207405. After the response of several members here, I went after the rest of the polish with dampened Q tips. Sorry for the suspense, but the cleaned up pic, will not load for me and I have no idea why it will not, I knew the first one was too easy! I will try to add it in another post here. Any chance anyone can recognize this work? I believe the serial number puts this one as made in 1968, so its been around for a while. My best guess is, that an owner had the copper plate added and maybe a subsequent owner didn't like it and covered it with the polish and eventually I wind up with it! Thanks for the help, still working on the cleaned up photo. - Thanks Bill in MA
