You don't see very many of the Lisk lanterns. Lisk carried a complete line of tin and sheetmetal goods in the early 1900's. I believe Lisk was a jobber on their lanterns by having other manufacturers make them with the Lisk name. I also believe yours was made by Pritchard Strong Company(PRISCO). The brochures of 1920's do not have hot blast lanterns like yours, but show cold blast lanterns that look like Embury's.
Maybe another collector will have more concrete information.
