Text is from website:2446. Consolidated A6, A6A, and A6B Turret Hydraulic Panel. Rarer than the turrets themselves, these are available for your restorations. Complete as removed from scrapping operations. I am surprised that more of these didn't survive as hydraulic "mules" in civilian service, but the instructions to charge the accumulator to 600PSI may have diluted some of the enthusiasm to use them!

The Consolidated Models A6 and A6A Nose and Tail Turrets
These hydraulically powered turrets were fitted to some B-24J Liberators. The Model A6A tail turret was found to be so successful that the Consolidated designers were asked to adapt the design to fit the nose section of the B-24. The tail turret power unit consisted of a 24 volt shunt-wound motor driving a spur gear pump working at 83 kg/sq c (1,200 lb/sq in). A relief valve opened when pressures of over 91 kg/sq c (1,300 lb/sq in) were reached, exhausting the oil to the return flow. A pressure switch on the delivery line brought in the pump when the pressure dropped below 77 kg/sq c (1,100 lb/sq in).
The pressurized oil was fed into an accumulator consisting of two halves, one of which contained the oil. The other was joined to the first by a rubber diaphragm and was pumped to 42 kg/sq c (600 lb/sq in). With compressed oil, this kept a constant pressure to the turret and compensated for oil used in the elevation ram.
The Consolidated turrets were rotated by a multi-plunger fixed-displacement variable-speed hydraulic motor, worked through a gear train which operated a cable drum. two wires were wound round the drum in opposite directions, the end of each being fixed to the turret drum. When the motor was actuated one cable wound as the other unwound, rotating the turret. The gun cradle was elevated by two hydraulic jacks controlled from valves on the gunner's control handles.
It appears this was for sale at one time for $1,500.
