Free for postage- a Gossen N100 lightmeter. Meter movement good, plastic body very good, case not perfect but OK. Not sure if the CdS cell works, however. Note that this meter takes two batteries. Weight 150 grams.
This used TWO PX625/PX13 1.35 V mercury cells. A schottky diode (for example- 1N5711) would drop the voltage from a pair of silver-oxide batteries to this range.
