John,
Nitropropane is manufactured by:
Angus Chemical Company
1500 E. Lake Cook Road
Buffalo Grove Road, IL 60089
Phone: 708-215-8600
But they do not sell is small retail quantities. However Angus is also the
major producer of nitromethane, so most of the folks selling nitro buy it
from Angus and could also get the nitropropane for you.
It's ability to be mixed with gas would seem to make it desirable for anyone
wanting to run in both gas and fuel classes with minimum modifications (if
it was on the list of legal fuels).
