Rocket Engine, Liquid-Fuel, Cutaway, R.H. Goddard

Cylindrical combustion chamber with welded on adjoining exhaust nozzle, with brass colored lip; rectangular section, 12 inches long and 4.4 inches wide, cut out along chamber side with edges of cut section filed down; curved propellant inlet lines on top of chamber and connected to squared off propellant inlet fairings on each side of chamber and at opposite sides of cut section; conical top brazed on top with internal threaded pipe 1.5 inches in outside diameter brazed to top of cone; four other, much smaller pipes protruding from cone and closure nut, not secured, around shaft on top of cone; smaller toy top-like projection, metal, brazed to top of cone with twopipes projecting from it, one with outside threads. Cutaway interior reveals blackened cone coming down into top of chamber, the backened color due to a test firing of this motor; small and thin wire hoop attached on nozzle, with a type of adhesive, with the number 55 written on the adhesive, and a similar hoop attached to projection from the inside of the cone, indicating that these hoops were used to display this motor in the past, probably at the Guggeneheim exhibition of the rocketry of Robert H. Goddard, held in New York City, 1948. Nozzle blackened down the interior, indicating it was fired; some green corrosion on top and around cone on top of chamber, and old remains of masking tape, mused to secure the motor while it was on exhibit. Some abrasive scratching inside the motor, indicating there was an attempt to clean for the exhibit.
