I visited the collection in February and did not see it. A google search makes it appear that it is still being restored (below)
The planes in the collection are 99% factory condition. The docents told me he’s a stickler for authenticity. That being the case, there must be lots of fabrication as there are no boneyards to scrounge for the 262

I did a little more digging and it sounds like it’s over in England. It should be real interesting as far as the engine modifications go. Very few people alive have ever heard a genuine Jumo before.
