CLS 1000 is the end-all of 5x7 heads. They are rare, but probably the best head ever built for 5x7.

The best part is the mixing boxes and the lamp/reflector combination. If the whole power supply fails, an emergency re-work would be to just power the lamp from 120 and a timer with the shutter open all the time. This would work for B&W.

I moved my L1840 with a single helper.
