The nonrecoiling parts included the trunnion block group, the feed box and feeding mechanism, the recuperator cylinder and bushing, the back plate group, and the manual charger assembly.

W . Hryniszak of Asea Brown Boveri in Heidelberg designed a recuperator that was added to the otherwise unmodified GT 102 design to produce the "'GT 103 " '.

In 1997 Solar Turbines introduced a ceramic hot-section design for the Centaur 50 and introduced a recuperator for the Mercury 50, in experiments conducted with the US Department of Energy.

Its distinguishing feature was the barrel, significantly longer than the 13-pdr's and, unlike the 13-pdr, the barrel was significantly longer than the recuperator housing above it.

Recoil and counter-recoil were controlled hydraulically by means of a piston and spring combination connected to the recoiling mechanism and operating in an oil-filled recuperator cylinder mounted to the stationary trunnion block assembly.

Modifications included shortening the gun's barrel and recuperator, making the trail lighter, and incorporating the new recoil system which had been developed to allow 25-pounders to be mounted in the Australian-designed Sentinel tank.

It was designed for one-man laying with both traverse and elevation controls and sights on the left . The recoil system was below the barrel and used a hydraulic buffer with a hydro-pneumatic recuperator to return the barrel to its firing position.

As a general rule a recuperator selected for a pressure drop of between will have a good efficiency, while having a small effect on fan power consumption, but will have in turn a higher seasonal efficiency than that for physically smaller, but higher pressure drop recuperator.

The recoil system is also being upgraded, as the legacy system had reliability issues with the recuperator, buffer, and variable recoil linkage ( which sets recoil length based on elevation ); it had a lot of moving parts needing constant maintenance and adjustment during operations with high replacement rates of spares that are complex to manufacture and require specialized tooling to assemble, increasing costs and causing availability problems.
