what is a control gland?
The things you guys call buttons?
The buttons have a stainless or chrome plated brass shaft that passes through an O-ring or O-rings, that is the "gland" of which I speak.

Now, really, did you think you had me? Try harder. I built a housing in 1968 with kit you could buy in Skin Diver, it came with two glands. I put my Rice Crispy camera in it and was able to take a few pics. Someday I will scan my thousands of slides or maybe hire somebody, maybe an illegal to do it for me.
