CFS Barons
Gents, I've only just discovered this posting!
I flew for CFS in WA from 1966 to 1970. Looking at my log book, it shows cloud-seeding operations out of Perth in 1967 in 95-B55 VH-CFJ and the following year out of Meekatharra (a real punishment posting that one) in 95-C55 CFB.
CFB (formerly BIB) certainly had all the bells and whistles; the only downside I recall was that as it had generators (not alternators) it was possible to flatten the batteries with the engines idling and everything turned on - as I found out to my embarrassment once.
Fris B. Fairing - the firebombing ops were conducted in 1969, operating mainly out of Manjimup. The aircraft used were 95-C55 CFG (as you said) and 95-B55 CFO. Barry Tate and I were often involved in this (another punishment posting!)!
