Optimus Swedish Lamp torch brass blowtorch, for benzoline fuel

Beautiful rare and early example of the Swedish blowtorch, dating to c. 1920s with beautiful art nouveau / deco style lettering reading ‘The Swedish Lamp’, along with other embossed notes in French and Russian and the Optimus trademark to the body.
Brass body with other metal (steel?) handle and torch grill. Adjustment handle is wood, painted black.
Note that operation of these older lamps requires separate ignition (there are plenty of videos explaining this online) and that only the specified fuel should be used.
Good condition. Note that one of the straps making up the grill has broken (see photos), otherwise in excellent condition commensurate with age.
Height approximately 18 cm
