Back in the 1970's, Beseler imported Topcon's and put their name on them, like Honeywell imported the Pentax and called it "Honeywell Pentax". The Topcons had a lot of professional features such as fast motor drives and (I think) interchangeable viewfinders. They were highly regarded camera systems but they faded away.

The rebranding of photo equipment is still being done. When I went shopping for a new enlarger, I tried to find a Saunders/LPL but discovered it was no longer called "Saunders". It's now imported by Omega and is called an Omega/LPL. Same enlargers, made in Japan by LPL.
