Hello All Thought I would throw this one in the only thing about this story is the carbide that goes into the light. In the past I have had the habit of going to old houses of people wishing to clean out and making an offer to remove unwanted items, paying them for the service. Anyway on this particular day the dearly departed gentleman had been an old time mechanic and his welding system was a complete and obviously still working carbide gas system for Oxy/Accetylene welding. And under the house was about 8 unopened 4 gallon kero shaped cans of carbide. No didnt get any, they went with the gear, believe they went to a collector in Kingaroy regards Al
