Strangely both sw marked Arcolectric , England and 110 lamp, generally only
building site kit would use this in England. Mains one dicoloured enough so
impossible to read colour bands measured 47K so both set for 110V presumably
.. Replacement ones have plenty of space to change the dropper, 1 150K as
original for 240V land , and the HT standby 150K dropper replaced with
560K//560K
