Mk.Ib aircraft had only the two cannon, while later production

planes also had four 7.7mm machine guns. After the start of production of the cannon armed version Mk.I, it was suffixed with

the ‘b’, amking it the Spitfire Mk.Ib, while the version armed

with eight 7.7mm machine guns continued to be identified as the

Spitfire Mk.Ia, and this included aircraft manufactured previously.
