Civil Flying Services had a contact for cloud seeding in 1969 over Victoria using Beech Barons. They also had a tip tanked Bonanza at Roma.
Correct re the Baron.
CFJ was one and there was one other, but cant recall the rego. CFJ was I recall, BIB at one stage when Bib Stillwell owned Civil. He later put that rego on his Lear.
Peter Bini did a fair bit of cloud seeding in the Baron out Nhill way for a few seasons. Barry ?? was another regular then... He later went to Civils in WA as did the Baron. And I think it was a bit earlier than '69. Maybe 67??
Yes, those days at MB were great.. nothing like today (sadly)
