These are the Gloster production statistics for 1937-40 from Putnams Gloster Aircraft.
1937 - 265 aircraft (12 Gauntlet, 252 Gladiator and one F.5/34)
1938 - 169 aircraft (158 Gladiator, one F.5/34 and 10 Henley)
1939 - 524 aircraft (320 Gladiator, 171 Henley, 32 Hurricane and one F.9/37)
1940 - 1,247 aircraft (16 Gladiator, 19 Henley, 1,211 Hurricane and one F.9/37)
In the past I've wanted to have more Hurricanes built instead of the Gladiator and Henley, but if the monoplane Gloster builds instead of the Gladiator was as good as we think it could be then it would make sense for Gloster to keep building it instead of the Henley and Hurricane. That probably means more aircraft built in 1938 and 1939 because Gloster doesn't have to tool up to build 2 new types of aircraft (i.e. the Henley and its cousin the Hurricane).
However, if the Gloster monoplane is as good as we think it could be, then the Hurricane and/or the Spitfire might be cancelled because the RAF usually standardised on one or two types.
In the middle of 1936 the RAF wanted 900 F.5/34 fighters by the end of March 1939 to equip a front-line of 294 aircraft (21 squadrons of 14) backed up by a reserve of 225%. IOTL it ordered 310 Spitfires and 600 Hurricanes.
However, ITTL at least 203 Gloster monoplanes were on order out of the 581 that were eventually built for the RAF and RN instead of the Gladiator. Therefore it would have been logical for the Air Ministry to order about 100 extra Gloster monoplanes from Gloster instead of the Spitfire. The Air Ministry could be more confident about Gloster completing the contract on time than Supermarine. The Gloster monoplane was already in production and Gloster had 15 years experience of building aircraft in those quantities. Between 1920 and 1936 it built 1,000 aircraft while over the same period Supermarine had only built about 175 aircraft, although many of them were twin-engine flying boats that were much larger and more expensive than the aircraft Gloster built.
IOTL the 310th Spitfire and 600th Hurricane were both delivered 6 months late.
