White Gas Blowtorch.
No name on this torch, just a model number of “A06AA”. Plunger does move, but the diaphragm is gone so it will not pressurize. Valve does not move, but does have a cool (possibly) bakelite handle. Body of valve is brass, with a nice patina. This one’s great to hold down papers or to remind that retired plumber in your life of the bad old days!
