I don't see how another feed dog would fit Mr Ugly's throat plate. Black paint would work - but Redbug is right, decoupage would match some of the kids that might buy and use that machine... it is no collector's item LOL... The hand wheel and the bobbin winder were modified by somebody. I just now put a big old hand wheel I took off a Singer 28 on it and it works great - now the bobbin winder and shield don't fit and the one off the 28 doesn't fit either. I love tinkering...
