On the rare occasion I get one correct you can take it as a given that open house is declared. Have no wish to hold up proceedings. With regard to the Hawk I understand the Hawk75 to be the export version and the P-36 the domestic (USA) version. Interesting that limited production (only a few airframes) of the Hawk 75 was undertaken in both China and India. Aircraft built by both contries were absorbed by the RAF as Mohawks. About the only photo I have, excuse the big head but should be easy.
