I've ended up with a 120v timer that I don't have a use for. The model is a Beseler Audible/Repeating Enlarging Timer. It has a switchable beep at 1 sec intervals for dodging and burning which is a nice touch. Can switch up to 500w with times from 0.1sec to 110 sec. Just to repeat: this is the 120v version so will only suit anyone operating a 120v enlarger via a transformer etc. It still sells new in the USA for around $250. Asking £40 + post/collect from London, UK.
