1950s Coleman Canada 300 series blowtorch made by Butler Stampings in Ontario Canada. The 300 series torches are typified by the large bakelite fuel control knob and heavy steel fuel tanks. Earlier 90, 100 and 200 series torches have brass tanks and metal fuel knobs. All the Coleman models seen have clear coated unpainted wooden handles and a fragile water slide decal which is often missing. These torches mainly show up in Canada but are occasionally seen on auction sites in the UK so would have been exported at least there as well. The bottom left image is the remaining Coleman decal, bottom right image is of an intact decal as would have been originally on the blowtorch.
