Here's an interesting helo I picked up. Hubley made this diecast helicopter sometime in the '50s and it was a nice addition to their line of diecast airplanes. The only thing is, while the airplanes were definitely based on actual planes this helo appears to be a caricature. I can find no photos of any helicopter that matches the outlines of this. The Piasecki YH-16 kinda, sorta matches it except that the Piasecki is r-e-a-l long when compared to this. What differs on the toy vs. the prototypes are two main features: the odd cockpit (there were some really unusual cocpit designs in early helicopters but the toy doesn't match any of them); and the air intakes at the bottom rear fuselage. The YH-16 does have air intake bulges sticking out from its fuselage but they're higher up on the body.
Anywho, the toy came in two colors that I'm aware of (yellow and blue) and two sets of markings that I'm aware of (star-&-bar and forest ranger). Often times the star-&-bar insignia is wrongly placed in an upside-down position. The star-&-bar insignia was used by all the services so you can make believe it flew for the Air Force, Coast Guard, Navy, whatever. The fuselage measures 9" (22.86cm) L x 1 5/8" (4.12cm) W x 3 3/4" (9.52cm) H The landing gear spreads out to 5" (12.7cm) wide and the rotors are 8 1/2" (21.59cm) L. Enjoy! Opa Fritz and Oma Bettina
