6x13 rollfilm back for 4x5

does anybody know of a 6x12 or 6x13 rollfilm back for a 4x5 camera, possibly as a Graph Lock back?

The Horseman 6x12 is good quality but has gotten a bit expensive.

Intrepid has a new Super 120 roll film system that covers 6x4.5 all the way up to 6x12. I have not used it myself

I can think of three (at least) new : MIA miapinhole.com (UK), Mercury Cameras (USA), and Intrepid (UK). I've only got experience of Mercury's offering, and have a couple of reservations about it. The Mia one lets you choose any size with backing paper markings, and Intrepid has this dynamic multi-format one.

Used, there are Horseman, DAYI, Cambo/Calumet. And probably others.

The one I use most is 3D printed from a design by Edgar Kech.

These all claim to fit a Graflok back via the usual sliding clips. The cambo slide in type does mean you do not have to remove the ground glass. But this is not an issue with a rangefinder camera, of course.

I am sure this list is as notable for its omissions, as anything!

If you really want to spend money, there is a Linhof one as well

ShenHao; Sinar Panorama, Vario, Zoom, Zoom II. The Sinars are all insertion type but have recesses to accept Graflok sliders. I have a 6x12 Panorama. AFAIK, parts for Sinar roll holders are unavailable.

I'm curious about the Intrepid and may try it out, its flexible and pretty inexpensive, but its worth pointing out that it requires assembly, so be sure to watch the assembly video to decide if that it worth it to you.

I think the Horseman 6x12 rollfilm back is your best option (I've had one for years) other than the even more spendy Linhof. But expect to spend around $500.

thanks for all replies... Linhof it is.

Bob Saloman (am I getting his name correct?) used to point out that the Linhof Techno Rollex was a true 120mm width. A fair bit wider than many of the others.
