AB Järnvägsmateriel
Stockholm, Sweden

This is the only picture that I have found of a blow lamp from this company. As you can see, it is in a bad shape with the control valve missing and handle and bar bent.

This company was active in Sweden in the beginning of 1900, specialised in supplying all kinds of equippment, including blow lamps, to railway companies. There is no evidence that they had any own production of blow lamps but it is belived that these were produced by another Swedish manufacturer, possibly Optimus.

I would be grateful if anyone can come up with more information about this company.

This picture shows the markings on the fuel tank.
