Hawker Hurricane pre-war losses

[WAKEN]

The first production flight of a Hurricane was on 12/10/37 with the first delivery to the RAF on 15/12/37. By the start of the war 497 had been delivered to the RAF. Does anybody have any information on pre-war losses in accidents?

Thanks,

How many of the 497 delivered were on strength with front line squadrons at the start of the war? For Spitfires 306 had been delivered by the start of the war of which 182 were with front line squadrons.
