Halo forum here is my latest purchase and restoration,A BLADON B62 lotampen fur benzine gasoline.
It was made in 1929 it is a realy good quality lotlampen, and very well made and has a special safety feature on the pump.
The non return valve on the pump is the same type as on the SIEVERT 221 222 and 223 etc,but has a special safety device, at the bottom of the pump shown in the close up picture,you have to press the spring loaded lever, when you want to pump the lamp up to pressure, to allow air in the tank and when you have finnished pumping you let go of it and it will spring shut.
So if the non return valve washer on the pump should fail no fumes or fuel can enter the pump tube.
the safety valve/device is at the front of the tank just under the burner nozzle.
All British blowtorches/lotampens are based on the sweedish design,but unlike the Sweedish torches most of the british benzine torches, i have seen the burner is permently fixed to the tank and can not be unscrewed,to replace the wick you have to unscrew a large nut on the bottom of the tank and pull out the old wick.
This lotlampen was quite difficult to get a good clean and polished finnish, which i like as the burner can not be removed from the tank, and the pump tube is fixed to the tank and can not be removed all so.
I have sprayed the steel handle with a brass colour spray as that was the original colour,i think every BLADON lotlampen, i have seen they sprayed the handles and the tanks with brass colour paint, even the tanks that were made of brass,were painted with a brass colour paint,here are some pictures of the BLADON B62 i will show some pics later of it working as i have more than five pics
