Bingo! How about this one:

It this one is not a Yak 17, you have me stumped. The Yak 15 was a tail dragger with exposed 23mm cannon barrels, so it cannot be that. The Yak 23 had a different nose gear door arrangement, so it cannot be that one either. To cool, I can't wait to see this ones identity.(I like getting stumped) Must look real close to the Yak 17 though, shot below definitely shows some resemblence, but cannot find another Yak aircraft that matches.
