I used to have a ton of the 10 inch ones which I think is the 4122. Still might have a couple back in the shed. Not much to them, just a reflector, a medium prefocus base, and a little blocking tube that swings up in front to the lamp. (The "proper" name slips my mind!) The screw/knob sets the distance from lamp to reflector to adjust the beam. Socket should be aligned so that the center of the filament is in the center of the reflector and the filament is flat with respect to the reflector. I think they took a 1k lamp (BTR?) As with all BPs, you will not get a clean even field of light, but it's not really intended for that. (More for a "sunlight through window" effect.)
