Yes. I have a 6x9 as well as the 6x7.

There was even a 6 x 12 made.
None of the Calumet's are as sharp as Sinar's version however.
This was from my own comparative testing of a Calumet 6 x 7
vs. a Sinar Vario Roll film back, ( version 1 ).
I discovered that the Sinar had an additional Roller along the
film's path, than the Calumet did.
BUT, Both of my versions BROKE !
The Sinar could NOT be repaired due to a shortage of parts &
the unwillingness of the repair person, to take a chance on
Version 2 parts.
The Calumet could be repaired & modified so it wouldn't
break again, ( basically substituting screws for rivets ),
but the housing got misplaced from the internals & thus
was never reassembled.
My Loss !
