He he. . .
I have in my hot hands (okay on the shelf, not actually in my hands), A 1/48 scale HH52A "Vietnam gunship" model by the Ringo Toy company. It is a really bad kit circa 1960's "Auroura style." With the place where the decals go already engraved in the kit, and the decals are for a Sikorsky demo helo to boot. . .
HOWEVER, The basic shape is there and with some heavy sanding the raised detal will be erased and I shall have a model of the HH52A, perhaps the 1405, the aircraft I was qualified in so many years ago.
I too have the book you mention and the thanks page is a walk down memory lane as I know most of the people.
BTW, I know of only one person who called it the SEAGUARD, usuall we just referred to it by the numbers.

I know it's only rock and roll, but I like it.
