I could find nothing in the background of the H16 to indicate where the picture was taken [...] I could tell from the cars in the background that the H14's were located in the USA [...]
You don't need to do as much detective work: as I said, those pictures are from Whirlwind,
on their page there are captions locating the H16 on Long Island, New York and the two H14 in North Carolina.
I've never had a comptip, when I was sailing my H16 in California it was an old model, with an all aluminum mast.
