How many Gauntlets were fitted with the Mercury VI S2? I thought the VI S was the standard for Gauntlets.

Alex Lumsden’s ‘British Piston Aero-Engines’ only lists the Bristol 105A, 133, 142 and Gloster SS37 (Gladiator) as having been fitted with the S2 although Putnam’s Gloster book mentions the S2 having been fitted to the Gauntlet.
