For all you advanced collectors here's one you very seldom see , especially in this condition . I've only seen a handful of these in 35 yrs. of collecting , this being the best of any I've seen . No pitting , rust , dents . It's beautiful . On the air tube it says Reg. Oct . 25 , 1915 & S ( Syracuse ) May 1921 . I believe this to be the last model hand lamp made by Dietz . Stands 8 " to the top of the chimney . Email any questions . THANKS !!!
