I just brought home lots of negatives and a few glass plates. They were my fathers who was a photographer for the USN during WWII. I have an Omega D2xl enlarger and have been making contact prints however I don't have any carriers for at least one of the negatives. Here are my guesses for the carriers. I have no idea what the film size was actually called but would like to know and what cameras used that size.
- 3 3/16" x 2 3/16" or 8.2cm x 5.6cm (I'm assuming these take Omega 423-361 21/4x31/4 or 6cm x 9cm carriers which I have)
- 4 3/8" x 3 3/16" or 11cm x 8.1cm (Don't have but think it will be Omega 423-315 3¼"x4¼" sheet film, maybe hard to find)
- 4 11/16" x 3 5/8" or 11.9cm x 9.2cm (Looks like my Omega 423-363 4x5 carrier works for these.)
- 9 x 12cm Plate (Have no idea how to work with these)
