Is This a Multi Format Plate Holder?

[Mike1234]

Sorry for my ignorance on plate cameras and accessories. I just never got into them. However, I received this as part of a package purchase a few years ago and I need help identifying its purpose. Thanks in advance for your help. Pics will be in two posts.

Overall dimensions are 11" wide x 11 7/16" long x 3/4" thick.

Four more pics...

Yup. The inserts allowed different size plates to be used on the same camera without changing backs. By the relatively clean appearance, I would guess the whole set was for dry plates, though I've seen them adapted for wet-plate work. Pretty nifty, huh? I have a set for my Rochester Universal.

Thanks, Whitey!! Any idea what it's worth? It shows some external wear but it's in great shape and 100 percent complete. Any idea what camera it fits? It seems to be an odd size.

[Whiteymorange]

No idea whatever. I'm sure there is a buyer out there somewhere, but the size of the whole thing makes me wonder if it's not specific to one camera, thereby reducing the potential buyer crowd to people who are interested in customizing - and the few owners of one particular (unknown) variety of antique camera.

Thanks, Whitey. That's what I was afraid of. This may be difficult to sell then.

I think if you measure it you will find the depth of the film plane consistant with modern holders. However it will be wider than a standard camera back. I know someone who cut off a certain amount off the side on a table saw to make it usable for wet plate.

Thanks, Jim. I'll check to see if this can be done. I think the width is about a quarter inch or a bit more too wide for standard 8x10... I'm unsure about the length.

[Jim Chinn]

1/4" sounds about right IIRC. If you decide it is not something you want to keep send me a PM. I would like to purchase it.

[Mike1234]

Will do, Jim. Thanks!!
