Yes, I do have a thing for the H-34, well really many of the early piston powered helicopters H-19, H-21, CH-37 etc. Just something about the awkward daredevil look they had, kind of Evel Keneval meets Waldo the dork.
I've got an H-19, H-34 and HUP-1 I'm close to finishing. I have another H-19, and H-34 waiting to go as well as an H-21 I've just got started.
I can't point you to any specific links but I know I've seen a similar pic to the one you posted but from more of a head on angle. You might try adding in some search words including Mercury, NASA, capsule recovery and the Mercury Astronauts Glenn, Shepard, Carpenter, Grissom, Cooper, Schirra, and Slayton to the more obvious H-34, Seahorse etc.
There is a NASA website with a bunch of photos including many of the capsule recovery operations but I haven't found its search feature very useful, besides after Mercury the Sea King was used instead of the H-34.
