Note that .........
(6), the .22 Pattern '18 rifle, has a British "U" marked bolt-head, relating to the material specification, and is a converted .303-inch CF component, being filled then bored eccentrically. It has the large .303CF extractor to draw the 303-cum-22 conveyor.
(5), the RFI rifle, has the less common late model ".22 No.2C" bolt-head.
(4), the No.2 Mk.IV* rifle, has the more usual ".22 No.2" bolt-head .
(3), the .22 Pattern '14 rifle, has the bolt-head unusually retaining the charger-loading slide of the No.1 Mk.I rifle that is often removed during conversion.
(2), the Rifle .22RF Short MK.II, has a later ".22 No.2" bolt-head possibly retro-fitted with the Hiscock-Parker magazine.
(1), the Rifle .22RF Short MK.I, has the expected early plain bolt-head, unmarked other than by the broad arrow and military proof on the rear face.
