Marx 666 Stamp

Does anybody know where I can get a 666 stamp for my Marx steamer? Thanks,
Eric

Aren’t those numerals raised on the cab’s surface?

Yep, they’re raised on the cab’s surface. So if you want to repaint, all you have to do is carefully paint the numbers white (or another color that suits you). If you want to renumber it, you’ll have some grinding to do beforehand.
