FIAT A 74 could be restarted in flight?

[greybeard]

I was unable to find on manuals of CR.42, G.50, MC.200 and A.74 itself any mention about this kind of emergency. They all describe that starting is performed by compressed air, stored in a reservoir bottle and generated by on-board autonomous Garelli compressor, this latter with its pull-starting handle "at pilot's fingertips", as mentioned by Pilot's Manual. During flight, an engine-driven Zenith compressor maintained pressure inside reservoir bottle.

So it looks it could be started in flight, perhaps even without apply Garelli, but exploiting available compressed air in reservoir bottle. But I've no evidence.

Any help?
