11x14 Fidelity Medical Cassette (11x14 Fidelity Film Holder)
Recently I looked to buy some NEW 11x14 film holders for my Deardorff and Seneca 11x14 view cameras. New 11x14 holders are very expensive and hard to find because no manufacturer makes them anymore. After extensive searches and long waits I was lucky that I found some new old stock of 11x14 Fidelity Medical Cassettes which are exactly the same as the regular 11x14 Fidelity film holders after the bars/ears that were modified for X-ray machine are removed from the cassette. The holders were well made in USA. Dark slides and septa are real metal sheets (not plastic) and unbreakable.

Fig. 2: Each 11x14 Fidelity medical cassette has two side bars/ears which are the parts with metal hooks
Fig. 4: Tools used to remove sides bars/ears are a Philip (crosshead) screw driver and a spanner wrench

Fig. 10: Four disks and four screws removed from each bar/ear
Fig. 11: Side view of holes after a side bar/ear is removed. There is no light leak due to those holes because the holes are not patent

Restoration of an Ultra Large Format 11x14 Improved Seneca View Camera
Part I: The original camera
I bought this camera and wanted to restore it. The camera frame looks good, but the bellows is bad and several knobs are missing, no rear extension rail.
This camera is about 100 years old and was made in Rochester, New York, USA. It weighs only 12 ½ lbs without the extension rail and constructed of mahogany/cherry with polished brass hardware. Focusing is accomplished via front and back rack and pinion movements. This camera has rising and falling in the front standard, swing and tilt in the rear standard.
Part II: Camera was cleaned and the bellows was removed
Camera without bellows
Bellow frames
Part III: Make a 11x14 bellows
Fabric: 2 layer Gore Tex nylon
Craft bond glue and poster board
Pleat design for bellows
Pleat printouts
Pleats are made from poster cardboard and are ready to be glued on to fabric
Folded bellows

Part IV: After installation of bellows
