U.S. Endicott-era balanced pillar and masking parapet mounts were, in a sense, a hybrid of simple pedestal mounts and disappearing mounts: the guns were hidden from observation while out of action, but, once engaged, remained vulnerable to direct observation and direct fire.
In 1893 Germany's Hermann Gruson developed an armored turret for a 53 mm gun called a "Fahrpanzer" (mobile armor) that had both road- and rail-mobile versions.
