I am going to go out on a limb,  They all have MAPP GAS(yellow),  3x the price of propane,not really popular, stinks like pure assholes...  These people were ALL SUPPLIED from 1 source,  I would check ties with " City of Los Angeles PLANT AND EQUIPMENT MAINTENANCE warehouses"  ..  That have MAPP GAS in stock,  and see if it is still IN STOCK in Said Warehouse..and if Self Igniting torch heads are missing too..
