I have seen a number of Model 21's over the years that had been poorly refinished. The refinisher purchases the beat up gun for a song and then sees $$ signs before his eyes and attempts to have the gun made saleable for as low a cost as possible. Once that is done the Model 21 is junk and not worth a single dollar as the cost to properly refinish (If it can be done at all) will far exceed the resulting value.
In other words 'junk will always be junk' or in this case 'weird will always be weird'.-Dick
