I acquired this lantern in March 2009 from an eBay auction. I selected this model as representative of the type I used when I began camping with the Boy Scouts in early '60's.
The lantern was not operational when I got it. There was some rust on the frame and scratches on the fount so I did a complete overhaul.
The lantern was completely disassembled and cleaned in a citric acid bath. The fount stripped and repainted; the generator, valve packing, leather pump cup and mantle were replaced. The filler cap was updated to the new model for safety (the original is still used for display).
The lantern burns beautifully now, another piece of history back in service.
