In 1937 Sweden ordered fifty-five British made Gloster Gladiator fighters, but requished thirty of these to the Finnish Government. The remaining twenty five entered service with Flygyapnet as the J8 and J8A (the latter having Nohab built 740 hp Mercury VII engines). During the Winter War between Finland and the USSR twelve of these Gladiators equipped the Swedish volunteer unit F.19 fighting along side the Finns.
