Skidbiter - Thanks and think KM used to also be Doug Maxwells for a while before going to Rosemary.
And the Eagle E model I saw down at Blenheim for the frosts, and think its now operated by company called Windhawk.
500Fan - I think that could be HTB or similar operated out of Rotorua in the old days, maybe by guy called Armstrong, but might be wrong there. Skidbiter would know of course
I think also the tuna boat 500 is a C model.
