Vickers F.29/27 (serial J9566) complete with military markings, serial and C.O.W. quick-firing gun in position. This version differs from the one published in having small fins fitted to the top and undersides of the outrigger booms. This modified design is believed to have been designated Type 162.
Built to the same specification as Westland COW Gun Fighter was the Vickers COW Gun Fighter, J9566. It was first flown on January 21, 1931. To improve longitudinal trim 60lb of ballast was carried in the nose.

The Royal Aircraft Factory N.E.1, or Night-flying Experimental, was designed in 1917 and was powered by a 200 h.p. Hispano-Suiza engine. Armament consisted of either a COW quick-firing gun or a Vickers “rocket gun”.
The Fairey N.4 variant N129 Titania was, in its day, the largest flying-boat in the world. It had a span of 140ft and a gross weight of more than 30,000lb. There were apparently plans to equip N129 with a COW gun - can anyone confirm this?
