There's a reasonably shiny PA38 at Chilbolton (Stonefield Park) airfield in Hampshire, which last I looked had an intact airframe and gear, but had been robbed of anything vaguely valuable or useful.
I don't know anything about it's ownership, but the airfield management is in Pooleys and it might be worth asking the question - it may be that somebody would be glad to get rid of it; certainly I doubt anybody would want to fly any of it again after it flew uncommanded (complete with concrete blocks) over three hedges and a public road in a gale a couple of years ago (thus possibly demonstrating the best climb rate ever seen from a Tomahawk).
Last I was there, there was also the remnants of a PA28 fuselage that had been robbed for parts behind one of the hangars at Old Sarum. Presumably if you spoke to Old Sarum Engineering they'd know if it was still wanted or not.
