Oleg,
If you want a very good source for various airplanes have a look at
http://www.hph.cz/index.php?option=c...id=102&lang=cs
The owner of this company has quality written all over him and is known to not do things that are not authentic.
I've visited their factory lately and was very impressed with how they do things.
Maybe you want to contact them.
