IS-2 Mucha Sailplane Model Kit
Very High Quality Resin Model Kit
Scale: 1:48
Wing Span of Full Size Glider: 15 m (49.2 feet)

The full size glider was designed and built in Poland starting in 1948. 
This is a very nice and detailed kit.

The excellent book Sailplanes 1945 - 1965 by Martin Simons includes an excellent write-up, photo and scale drawings of this glider.  A quote from the book, "The second sailplane designed by the ISZ group was the IS - 2 Mucha (Fly).  It was intended for club use, replacing the Komar, but had a good enough performance for cross-country flying and simple aerobatics."
