M E Cleverley

I have an Exley 00 LMS 6-wheel corridor passenger brake, usually known as a 'Stove'. It's a bit worse for wear in particular the metal sides/roof/side wrap are detaching from the chassis and the glazing strip on one side has detached within the body. Although I'm a reasonably skilled scratch builder I could do it more harm than good so I'd like to get it professionally restored but don't know who to contact. Any recommendations please? I believe in recent times Edward Exley offered a repair and restoration service but that has since been discontinued.
