Question: Which was released first, Gunner Palace or War/Dance?
Context: The Scarff ring was a type of machine gun mounting developed during the First World War by Warrant Officer (Gunner) F. W. Scarff of the Admiralty Air Department for use on two-seater aircraft.  The mount incorporated bungee cord suspension in elevation to compensate for the weight of the gun, and allowed an airgunner in an open cockpit to swivel and elevate his weapon (a Lewis machine gun) quickly, and easily fire in any direction.  Later models permitted the fitting of two Lewis guns; while this doubled the firepower available, operation of the paired guns was more cumbersome, and required considerable strength from the gunner, especially at altitude, so that many gunners preferred the original single gun - and this became the postwar standard.  In either case, the mounting was simple and rugged, and gave its operator an excellent field of fire.  It was widely adapted and copied for other airforces. The Aerial Gunner Badge was a military aeronautical badge of the United States Army Air Forces and was issued during the Second World War.  The badge was first created and authorized on April 29, 1943 to recognize both the training and hazardous duty of aerial gunners, who manned defensive machineguns on board such aircraft as the B-17, B-24, B-25, B-26 and B-29 bombers.  The Aerial Gunner Badge appeared as a standard observer badge, upon which was centered a winged bullet.

They were powered by twin engines mounted on short struts on the lower wing in tractor configuration, and had fixed tailskid undercarriage.  Many of the subtypes were also equipped with a nosewheel to protect the aircraft and its crew from "nosing over" accidents while landing.  The pilot sat in an open cockpit, with tail gunner in an open position amidships, and a third crewmember in an open position in the nose where he could act as gunner, observer, and bomb-aimer.
