Navy YSH-2E Seasprite LAMPS (Light Airborne Multi-Purpose System) Anti - Submarine Helicopter, from Zlymex. This is a very nice vintage Kaman Seasprite die cast chopper from Zlymex. This is the more unusual YSH-2E model with the large chin mounted radar. This helicopter is SOLID Die-Cast metal (no windows, they're part of the metal cast), with plastic rotors and external fuel tanks on the sides. The fuselage is a little over 3 inches long, and it's in overall very good condition. This is a very unusual version of the SH-2 Seasprite, a general purpose helicopter that has served in the US Navy for several decades. Thanks for looking! Check out my Store!
