Rocket Sled, Liquid Fuel, RS-1

Long, rectangular-shaped, with large, rusted brown single flared nozzle and adjoining combustion chamber at end, with thin aluminum pipes and other associated plumbing in back of flat back of chamber; main part of sled consists of long silver-gray rectangular box running length of the sled, behind the back of the engine, this box holding the remaining plumbing of the rocket engine; box hinged on both sides for easy access to engine and sled instrumentation; triangular front of box; box originally painted white with black patterns on both sides, but paint now largely faded; underside of sled box attached to long propellants tanks one of each side (one tank probably for fuel and other for oxidizer); two swept-back white horizontally-mounted clipped triangular wing-like projections on front of sled, one wing on each side; bow-shaped cross bars underneath front wing assembly and matching bow-shaped cross bars in back of sled and underneath engine at rear. . By opening up a panel on the right front (facing the front of the sled), it is possible to look down its interior the entire length. This space is hollow except for a small and very rusted mounted electronic box towards the front. Because of its placement, this is believed to be a type of control for the test instrumentation of the sled (i.e. for mission experiments).
