Volume no.6 of the Profile & Scale series illuminates the various Polikarpov fighters of the Spanish Civil War (1936-39). More than 70 full-colour profiles document the appearance of these famous I-15s and I-16s, or Chatos and Moscas, in unstinting detail and accuracy. All-original, never previously published 1:48 scale line drawings are provided for the I-15 from all three manufacturers, Russian and Spanish. Full scale plans are included for the I-16 Types 5 and 10, but also for the special Ispanskii hybrid version shipped to Spain and the locally built examples from Alicante. The work contains more than 70 full colour profiles depicting all of the known Polikarpov examples from the photographic record. A discussion of tactical markings and technical development make this an invaluable reference for the historian and modeller alike.
