When a modeler has spent their hard-earned cash on purchasing a state-of-the-art resin kit such as the fabulous 1/72 scale Sikorsky S-39 by our very good  friends at CMR (Czech Master Resin) then what he needs to complete the job is excellent reference material, and what better than this! Our prolific Russian based correspondent Igor Kolokolov, on his World travels, has again come up with a classic walk-round for us of the aptly-named  beautifully restored S-39  'Spirit of Igor'. In itself a massive achievement, taking 40,000 man-hours spread over the last 40 years, she is today the oldest surviving Sikorsky in the World and is currently based at the Planes of fame Museum in the USA. Our grateful thanks  goes to Igor for his time and trouble to bring us such a superb walk-round. Thanks, Igor. (Hey, Igor - get it! This walk-round truly is the 'Spirit of Igor'!!)
