I have one of these backs, but I don't recall offhand if
it's a 6x9 or 6x12.
I have an older model. I had to work a bit on the light
seals before it functioned without light leaks. That
issue may have been corrected in later models.
One thing that you might want to check is whether or not
this rollfilm back will work with your 4x5. My back is
too large to fit in any of my springback 4x5's. A
Graflock back that opens wide is needed to get the
rollfilm back in place, and I have to be very careful to
not scratch any plastic screens involved.
My old Calumet view camera with an opening bail is the
perfect mate for the older version of this back.
For what it's worth.

It has to be 6x12. It uses 120 roll film so the maximum
width is 6cm. It might also do 6x9 which may be what you
meant to write.
I can't quite make out from the photo on ebay how its
made. If one roll comes off it may be possible to use it on
a spring back camera. Such adaptors were available in the
1950s. If not, it will work only on a Graflok or "universal"
back where the ground glass spring panel can be entirely
removed.
I have a Calumet C-2 roll adaptor. It was meant to fit
Calumet spring backs which are different from the older
Graphic back. Its thin enough to fit into a Graphic but on
older backs the "ears" will interfer with its seating fully.
These are 6x8cm, same aspect ratio as 4x5 and get nine
frames on a roll. They also take 220 film, which was, in
fact, designed for this holder.
