Sorry not to respond to your request earlier. One of my friends let me know of this question.
We use the Hancock #9 lifting inspirators of the E and A types. Also the Hancock HNL non-lifters of the 5000 gals capy. I will check further on this jsut to be sure.
Bernie at Backshop E., may have some inspirator parts but may not fit the #10 lifting.
Are you just looking for tubes & nozzles or are there other parts too?
At this point we really don't have spares (tubes & noz's) except for a gun or two of questionable condition.
Drawings are not available at this point.
#10 Type A's are good for 4050/4060 GPM.
If you send your old tubes to Bernie he could compare them to the 3500 GPM ones used in the HNL's. It might work for you if you aren't weorking to capacity. Some of the tubes & nozzles were used on both lifting & non-lifting.
Nathan material I can help you with. Hancock hardly let any engineering out of their control.
Ok to contact me if you need further info.
