Hi all, I'm part way through restoring an old Houghton-Butcher No. 7 Ensign Carbine (early1930's?). The shutter (Compur serial number 2110823) and lens (Aldis Uno anastrgmat 4 inch f4.5) have all come apart and cleaned up nicely, but the body is in a bit of a state. The bellows are light-tight but I'm missing a few small screws from various places. Aside from finding a donor camera, anyone know of any good places to pick up small screws in a variety of diameters and lengths? I'm assuming as it's a British camera that they will be British-Stardard (probably British Standard Fine).
