Fiendish Fabrications have added the Captain Boadicea miniature to their online store.
From their announcement:
Captain Boadicea of the Imperial Aero Corps and commander of the Aeronef: Chariot of Fire - is the first of our planned August releases. During this month we have some interesting (to say the least) miniatures, a new range of bases as well as the second part of our square Forest Floor bases.
