Airacobra Mk.I nose machine guns

[arek]

Does anybody know how many rounds of .303 ammo for the nose guns carried Airacobra Mk.I in the British service?

Only reference I can find is the P-39D carried 1,000 rounds per .30 cal gun. The "D" model is the one the UK used IIRC so the .303 capacity "should" be somewhere in that neighborhood.
