As with the example to the left, the handle has the same spindle fixing, but the normal seven and a number / letter combination 4Z, 5Z, 7Z (and possibly others), such that examples AT over Z, AU over Z, them apart from that on the filler cap (and in some cases the pump cap) which was stamped F W Lindqvis t I would also avoid the constant soldering elongated blowtorches if you come across these as they are more cumbersome. E.g. Primus 603 is a very nice and compact lamp for being a "real" blow lamp. A tad bit smaller than the 605 Nils mention, but still of the more powerful type i.e. with a good coil vapouriser and a cast iron nozzle instead of that flimsy all brass flame tube the smaller soldering lamps has.

It is by no means certain when the model names / numbers combination was open to speculation and discussion. Carl Anders Lindqvist took out a patent for a pressure stove burner

Where this occurs, as far as is known, the date code is always to be found on the underside of the blowlamp examples are of a small jeweller’s type, with Monument Brand stamped on the base of the tank. No other forms of filler cap, and handle fixings to the tank, appear on pint models. On the examples above left and

These fires are often responsible for thousands of pounds of damage in property and business loss. I think I only have Swedish blow lamps, but I would say that any of those brands will do if you can get one.
