Are the scales lucite ? Could they be celluloid ? More likely I think. I've seen celluloid shrink on pocket knives from the 1920s and '30s. You can see it pulled short of the bolsters and sometimes cracking between the rivets. Some, not all, so I assume some mistreatment. I've had more than one razor that came with the point rubbing the wedge a bit. Appeared to be factory celluloid scales but could have been replacements.
