Hi All This is the H1 version of the Vapalux do-nut type lamp. At the moment I know of only two of these, this one has No 182 on plate on top of reflector and the other one I have seen has 107 so that would indicate there should have been at least another 180 of these made. The burner unit is made of stainless steel with aluminium flange fitted, the glass is same size and style as one used on other later Vapalux lamps but with slight lip on top rim to sit on top of reflector to hold it up.
I think it's quite possible that W&B could have started the numbering at 101 to avoid leading zeros e.g. 001, 002, 011, 012 etc. which would mean that there should have been at least 82 of these made, probably more. There's no way to know until one of lamps 001 to 099 turns up - which seems highly unlikely to say the least! Anyway, this beautiful lamp now resides in my collection...
Cool !!! i like the design which enables it to be much more practical than the hanging donut lamps 1960’s… do you think this was produced with a possible MOD supply in mind at all? regards pb
