Carriage and recuperator, or recoil mechanism, together are known as the mount.
Even with the delivery of the first recuperator, difficulties did not vanish.
It was in the making of the recuperator systems that the greatest problems were presented.
Not until February, 1918, were complete drawings and specifications of the recuperator received from France.
The praetor delegated his power to three classes of judges, called respectively judex, arbiter, and recuperator.
By "complete units" is meant gun body complete, carriage, and recoil mechanism or recuperator.
That is precisely the equivalent of the feat performed by the recuperator of a 240-millimeter howitzer after a shot.
