This is a first model new line with a 4 digit serial number. 7-shot 22 cal revolver. Frame is nickel. This one has a very pleasing patina to it. They had a 2-1/4" blued bbl. This one has quite a bit of original blue remaining. Nice markings. Quite a bit of blue on cylinder also. Bird's head rosewood grips in near excellent condition. The action works. This is a very old revolver in remarkable condition.
