Many pages of paperwork later, Mark finally got the Parker Macrospray ITAR ( International Treaty of Arms Regulation) regulated fuel spray nozzles for the Motoman Flamethrower. Note the restrictions listed on the invoice.
These are test nozzles for combustion research. The same macrospray design is used in all the latest fighter jet engines. They generate 99% optimum fuel particle size for best combustion. Perfect for kick ass flamethrowers.
