From talking to folks in the warbird world, the folks in Russia are really running a racket with the recovered airframes.
Lots of stuff turning up and being offered to the highest bidder. Apparently there are lots of hands in between that want their share too.
That being said a few 110s have come out, a number of Hurricane wrecks. P39s, P40s, P63s, a FW189, a 190A5 in remarkable condition, numerous 109 wrecks plus the Russian wrecks. I've seen photos of a lend lease Spit IX that came out and its at Duxford with the Fighter Collection.
The Hunt brothers in England have the wrecks of 5 P63s, an A20, a Kate and some other Japanese stuff that came out of the Kurile Isles as well as elsewhere in Russia.
Depending on who you ask, the B25 that was interned in Russia from the Doolittle Raid, may or may not still be around. There have been other wrecks found of lend lease stuff as well. There is some suggestion that a couple of 617 Lancs that were left behind after a Tirpitz raid may have survived, as well as stuff left behind by the USAAF on the shuttle runs.
In the end it all comes down to big bucks....which I don't have
