I recently acquired a box of Airco Radiagraph parts (the Radiagraph was Airco's track torch burner). Most are new old stock but some are clean pulls. I have parts for the Lee Electric Governor, for the main drive motor, for the transmission, and some parts for the big forged bronze torch holder units. I also have spare Airco machine torches. I also have a clean scan of a manual/parts list available.
If you need parts contact me and we'll work it out. I'm easy to deal with.
