Picked up 39th TCA convention Bucyrus Erie crane (year?) and a broken burro crane (new lionel not old) that I will put on the layout as static features. I wanted to remove certain lettering on the cranes while retaining other lettering. I could repaint the cabs, but would lose all lettering. I assume that the TCA and Lionel markings were rubber stamped and if that is the case what will safely remove it?
