Its also worth remembering that while the case sizes are the same for the 3\" 20 Cwt and 77 mm (76.2x420R) they not the same gun and fired different projectiles.
Whilst its true that the O.Q.F 77mm was based around the 3 20 Cwt case, the ammunition was specific to the different guns. The Churchill 3inch Gun Carrier did use the 3 20 Cwt gun as its main, and only, armament.
