Hi Dom,
Send me an email at
tomillward@hotmail.com. I'm only up the road in Lyneham. I don't know much about Windsors, but I'll happily cast my eye over it and I'm happy to help where I can. I could even drive down in the Jeep and give it a airing.
I think the guys at Cobbaton Combat Collection (
http://www.cobbatoncombat.co.uk) in Devon have a very complete Windsor if you need a reference vehicle.
Regards,
Tom
