This collection of parts were all found in vicinity of the Nordhausen manufacturing facility. parts include servo crankcase caps -top left, electro-magnetic switch installation plate - middle top, crank bearing covers - top right, gear pump blocks with base - centre, and crank-shaft, piston rod, and hydraulic piston - btm left. The deep recess on the piston circumference is for a rubber seal and is an interesting variation in ring seal design (at least 4 variations of piston design were employed, with three designs flown on combat missiles). A valve tilt seat is visible a little to the right of the piston. A broken servo mount stabiliser is shown - middle right. The cast piston rod, top right, has not been drilled and milled - the part is 'raw' as supplied by the manufacturer before machining has been completed. Normally the manufacturer's details are machined off the metalwork - but not in this rare case. The three letter code gfa is clearly visible on the part and stands for the firm of Otto Fuchs Metallwerke.
