Notice it and G-BSMD - the one restored and back in the air a few years ago - are/were registered to the same person.
Looks as though it might be a bit difficult to trace which bits of which are now in the airworthy one without looking at the logbooks.
And, knowing the reason for the request, the owner might be reluctant...
And, of course, it must be added, the registered keeper may not be "the artist" you refer to, and may have bought in good faith.
