Yikes!! You have to give him credit for bringing it back into service, but no more than that. His metal refinishing methods are crude. His wood refinishing was a token gesture and the brass accents look like crap. There was little or no attention to detail. That was an awful lot of work to turn a worthless gun into one worth $100. Admittedly, based on the time commitment alone, refinishing guns is no way to make money. But, done with a little skill and a lot of care and attention, refinished guns can be a source of pride for decades to come.
Not only would I not be proud of the result of this work, I'd be ashamed to admit I had anything to do with it. Certainly wouldn't publish my work on the internet (I noticed that his face doesn't appear anywhere in the video).
