Real fun starts when you find a Linhof plate-holder-to-international-back-adapter.

They only take Linhof plate holders...

The worst thing? They work. And they'll even take the too-thich Slavich glass plates!

The "non-standard" nature of these things is becoming ever more clear to me with every purchase. Latest? I just bought Zeiss 9x12 plate holders, with film adapters for my camera. I was happy with the price and they fit the camera beautifully. When I went to put 9x12 film in them, it wouldn't fit. The adapters inside, made in Germany, are marked 725 1/4 (?) and take 3.25x4.25 film. They also require some backing since the middle of the film holder is open and the small metal "fingers" that keep a glass plate steady are free to press forward on the film.

Go figure

Congratulations, Whitey -- you're close. That marking is probably 725/4, and as I recall the /4 is the designation for quarter plate, aka 3x4. You want /7 for 9x12. The 725 model is, IIRC, a holder that fits a Trona or other Zeiss-Ikon slide-in back (derived from the Ica line; the Trona was sold by Ica before the merger). *IF* the adapters come out like a plate, you can just replace them with 9x12 film sheaths; if not, you need 3x4 film sheaths. You can, with the adapters especially, also get away with a sheet of thin glass or metal, maybe even plastic, to back the film.

Yup. Replacement is in the works, since the basic holders are in great shape and the sheath is held in with a spring clip. I actually have enough of these plate adapters to start thinking about making my own sheaths ( about 14 now.) The sheaths seem to be harder to find. I could use Ole's jam method, but I'd be tempted to lick the glass when changing film!

The 725/4 is correct. A little corrosion made it hard to read. Thanks!

If you want to use the jam method and avoid temptation, you can buy 3-M Post-It type repositionable low-tack adhesive in a spray can. Spray the plate in daylight, let dry, and then it'll be good for half a dozen uses before it needs cleaned and resprayed, perhaps more.

I have *one* spare film sheath I could send you if you need a pattern for making some -- and I think if you had a means of making those that wasn't too labor intensive, you could actually sell quite a few of them for a couple bucks each (I'd guess a minimum of a couple hundred, maybe as much as several times that if you had a cheap means of getting the word out). I've got some ideas, but it's about Project #124 on my list, and since I have enough sheaths for my holder stock, and no plans to buy more holders, it's very non-urgent for me.

Thanks, Donald, but I have enough of the things to use one as a template. The tinkerer in me wants to reinvent the suckers but I have to admit to having far too many projects to get involved in another one right now (Yes, dear, I will replace the kitchen cabinets this week.) Fortunately, I have a (retired) tool designer as a brother-in-law who may be up for a fabrication challenge.

I have an etching press, so I can roll sheet metal into a form and then use a small break to fold the sides. Shoudn't be hard.... ( he says as he ignores his wife's plaintive cry " Noooo Whitey, not another project!)

They say that the drug companies are working on a sequel to Viagra: Projectagra, which keeps a man from starting a project until he's finished the last one. Hope they fail.

By the way, I have one two-sided 9x12 film adapter that is labeled Filmel, Boston. It's a bit long for the camera I have and the flange is a bit thick for the channel on my Rietzschel Clack. I can make it work, but it may be better for someone else. If anyone is interested, I'll post specs and a photo. No charge but postage if someone can use it.

BTW, if anyone needs plate holders for the Voigtlander Avus 9x12 or any of its German cousins with the same back, the Fotokor holders fit, and are really cheap. I got mine from Alex-Photo on the auction site.

What about the double sided variety, do they fit the European cameras? I'm trying to find ones that would fit an Ihagee Duplex 9x12.
