I just picked up a Cyma Bumper, not sure of the date, but it's ~1950'-60's. This is my first Cyma and I was surprised to find that rather than a crystal, it has a plastic dome. The thing is so clean that it can't possibly be the original...it doesn't have a single scratch, which cannot be said for the case.
My question is this...what did these come with, from the factory? Was it a crystal or was it plastic?
I've looked at pictures of others, none that are exactly the same of course, and I saw one that specificed an "acrylic" crystal and another a new "plastic" crystal.
I haven't seen many, but I've seen a few Cyma owners around here, so anyone who can answer this, I will appreciate your help!
