Export restricted (ITAR), sale only to US Citizens and Organizations. Unusual double-sided rocket nozzle, evidently a developmental piece or prototype that Marquardt was working on but did not reach maturity. The piece features two engine nozzles, measuring 2.75″ across and 3″ tall, attached at the center of an 8″ plate, with propellant pipes extending from either side. One nozzle is stamped "Grinneli 2 1/2 x 1, WP347, S-402," and a cardstock Marquardt Company tag is attached to one of the pipes. In very good to fine condition.
