I have a Recommar 33 and a Voightlander that uses the same film holders. Believe that ICA used the same size. Keep your eyes open on Epay, these come along often. Most of the holders I have bought had the film sheaths in the holders. Many were sized for 3 1/4 x 4 1/4 inch film. You can figure on replacing the light seal on the top of the holders. Go to a fabric store and buy a good mohair fabric of the correct thickness and dark color. You will need the sheaths for loading the paper or film in. Have fun, Steven.
