The Avia S-199/CS-199 was a post-WW2 development of the successful Bf109.
After the war Czechoslovakia found itself in the possession of a great
number of Bf109 airframes but lacked engines. As a stop-gap measure to
quickly rebuild their air force, they took surplus Jumo engines originally
used in Ju88 and He111 bombers and put them into the Bf109 airframe. The
Jumo engine had roughly the same horsepower but was geared differently
than the Daimler Benz engine originally used, resulting in a broader paddle-bladed
propeller being used. This resulted in a plane that flew, but it was nowhere
near the performance of the Bf109 it was based on. Nonetheless, it served
its purpose and even saw conflict in the hands of the Israelis in 1948.
This book gives a close look to the plane through many detailed color
photos of a restored S-199 and CS-199. No stone is left unturned, no panel
left unopened. If you want to scratchbuild a 1/24 S-199, this book will
give you just about everything you'd need in terms of detailed photos.
Coupled with the photos are sectional drawings and obliques showing interior
structures as well, although there are no general arrangement drawings
included. Some color profiles round out this book. All in all it is an
outstanding reference book on this little-known extension of the famous
Bf109.
