I agree with Walter
about the Grafmatics. I use several instead of carrying lots of 4x5 double darks. For things that are about 70 years old they work perfectly but only if everything inside is also perfect: septums straight, film "grippers" tight but not too tight, main springs not weak with age, felt strips not loose, and fully dusted out.
A few years ago I went on a Grafmatic buying spree to discover a lot of sellers don't know what they have. The correct catalogue number is 1268. The other Grafmatic number 1168 looks nearly the same but fits only the Graflex SLR and not the usual Graflok 4x5 back. I paid about $100 each but recent values may be crazy.
Loading, using, and unloading a Grafmatic admits of no errors. Instructions for reference: https://www.graflex.org/speed-graphic/grafmatic/
