Any numbers on the white base of the lamp? Like, 7371?
The transistors could also be 2sc945 or 2sc1815, I think.

LDRs are seldom labelled. There are only 3-4 kinds...

Well, the 7371 is probably a good guess. What kind of power supply does it use? 18v wall wart?
Those photocells look a little different than some of the ones I've used. I really want to know what the fifth one next to the lamp is doing!

Is there a led on the outside that indicates the speed? and if so, does its brightness decrease when turning down the depth? Cause I used a 5th LDR in series with a speed indicator led on my first failed univibe attempt, Im guessing this might be the case here aswell.
