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.
