Information on Mentor SLR Cameras?

[AveryMiller]

Hey folks!
I recently found out about Goltz & Breutmann's Mentor SLRs. I'm super into Graflex's large format SLRs, but I never heard of the Mentor line of cameras!

The Mentor Atelier camera seems like an absolute beast, coming in a variety of formats. One problem-- I can't find a thing about these cameras! This article is informative, but I can't seem to find much else online about Mentor cameras, much less the Atelier variety.
I'm curious if you have any information or resources on these things!

Thing is, with that arrangement, the image will be still upside down and reversed in the viewfinder. Of course this will be comforting to know for the hard-core view camera user that will expect that orientation!
