Vintage Meccano A3 power control unit, tested and working as shown by meter, meter not included The red light on the front does not light up, unscrewing the lens I cannot see a bulb underneath, I am not going to unrivet the box to investigate I think this might be from 1958 or so, that's the date of the price list included in the box, can't see a date on the device or the box but it was box producing voltages as shown on appropriate outputs, a and dc, in very good cosmetic condition, cable and plug look old as expected Paperwork as shown, interesting, box tatty, damaged at edges, I'll add extra packaging It'll be well packed and sent promptly by tracked service thanks for looking
