Seems your dad had plenty of guns, and that you aren't too attached to this one. Like others have said, I would dispose of the gun. That said, I'd pull it apart and keep all the parts (maybe not the modified cylinder and barrel), especially that sideplate which has the FTR stamping - that gun has likely had an interesting history. You could probably buy a six pack or two for what the grips would sell for around here . Welcome to the forum, and if you decide to take it apart, you can find plenty of vids/how to's out there. Some folks have trouble with side plates - and some side plates are tougher to get off than others, but I've found once you remove the screws some gentle rapping of the butt with a hammer handle will slowly vibrate it off.
