I thought one could contact Murphy Aircraft, and for a one-time $100 fee, be added to their customer service list. Which then, of course, means one could get the build manual from them.
Naw she went to Ontario and had an unfortunate landing mishap on arrival, everyone OK and she’s being rebuilt. Wasn’t an amphib thing just some bad luck they had with waterfowl.
As for the hard copy manuals, I’d be very surprised if Murphy would send you all five manuals in hard copy for $100. There’s several large phone books worth of manuals, the shipping alone will cost me $75 to the states.
