FWIW, I have recently come to know Lee Maxted-Page, because he has gone into business with an old friend of mine, Andy Prill. In fact the business is now called Maxted-Page and Prill, but the old name is used for the car sales website (Andy is now in charge of the service side).
I went and visited their facility back in November, and it's really fantastic. It is located in a couple of old barns on a centuries-old farm way out in East Anglia, about an hour, hour and a half outside of the center of London, not far from Duxford off the M11. At the time they still had 1101 as well as 1080 in there. 1080 isn't for sale; the owner bought it and then lost his racing license due to health issues, so Andy has been drafted to drive it for him. :>)
Anyway--Lee seems like Good People, and you can see that the metal that he moves is all first-rate, and the clientele is quite discerning.
As to whether or not he would consider taking a 'replica', that remains to be seen. I recognize that yours isn't your average GT40 replica, but you would probably have to convince him of that fact before he would consider taking it on.
FWIW it seems that cars in the UK are selling for MUCH more than they are elsewhere, perhaps due to the strong UK pound versus the dollar. You could probably see a substantial increase in your sales price.
As for shipping the car over there, it just so happens that the largest high-end car shipping company in Europe, CARS Inc., is located just over the hill (on another farm no less). I also know the owner of that outfit, as he and Andy vintage-race a Porsche 356 together and I've visited with them at Monterey, Le Mans etc. Should you decide to send your car to Maxted-Page, it would make sense to ship it via CARS if for no other reason than the fact that it's so close by.
Cheers!
