Had an opportunity to buy a handfull of pocket lasers the other day. These are marketed as a "laser keychain" and measure 2-1/2" long by 1/2" in diameter.
I had remembered that Kalart made an accessory for the Kalart rangefinder equipped Graflex press cameras that used a battery and focused lamp to project a pair of light beams for focussing in low level light conditions. When Kalart manufactured its own press camera, the Kalart 3 x 4, this device was an integral part of the camera. So, the question arose - can a small laser be used thru the rangefinder port to provide low light level focus? Well, I tried it and it works. The only problem is to fabricate a fail safe blocking plate that prevents looking thru the rangefinder when the laser is in operation. Perhaps a slide switch arrangement? The cost of the keychain lasers - at the Englishtown (NJ) flea market $2.00 each including 3 LR44 batteries.
