It is a longshot but you may find someone who has or can reproduce those logos. A couple of years ago I found someone who had re-popped the original Checkmate logos. He had mentioned this in a post on the Checkmate community website. I contacted him and he was able to sell me a couple as he had a way to get them reproduced. I never did not find out how he did them, maybe CNC, injection molding or 3-D printing. They were exact replicas that he originally had made for his project. The price was not cheap but it was not outrageous either.
My other alternative was going to be to have a graphics company create a decal that looked like the badge, not ideal, but better than nothing.
I work for a large university and I know through some samples that our college of engineering has the capability to reproduce something like that. I never pursued a way to have them do it for me once I found the other source.
I have seen in the vintage snowmobile hobby where a group of folks get together to have a part reproduced spreading the setup costs over a greater number of customers. Depends on the interest in the part.
