This is a bit off track...but...I buddy of mine who went thru Canadore said he was in Dallas at Bell getting a 212 wrenching check out when he was asked if he wanted a 214B check out and a job in Iran...which he took them up on...this was in 1975. What he told me was very interesting.
I used to be part owner of a superhuey. Kinda sounds like what you are talking about 212 commercial nose and drivetrain But a military airframe with -709 engine. It was originally built by Helipro for San Bernardino Sheriff dept. but they backed out. We eventually sold it to an outfit operating in Afghanistan
