I've also bought another camera: a Sanderson 5x4 hand camera. I don't know how o ld it is, but there is lots of teak, leather and brass. The back has two sprung- steel leaves. The supplied wooden film-holders have grooves or slots down each s ide along their lengths. Sliding a film-holder in, the steel leaves on the camer a fit into the grooves, thus pressing the holder against the camera.

My problem is that my Fidelity holders don't have these grooves, so they can't s it in the correct position. I could remove the leaves, but then the ground-glass back couldn't be held in place. Only three wooden holders came with the camera.

Does anyone know if all 5x4 wooden holders have these grooves? Is this a standar d feature on old cameras? If so, I can just find a bunch of old holders. Or can Fidelity (or other) holders be machined to fit?
