When do you need it by? I'm flying out to my granddads in 6 weeks, and I know he has loads of old railway photos from his area growing up. He grew up near Bath so if my geography is right he wouldn't of been far away, so may well have some covering the Transwilts in the 40s.
I'm afraid I'm looking to fill a gap in a Queen's Birthday display that's come about because of that problem with the previous picture ... would be very interested in 1940s pictures later next month, yes, but alas not for current need. Thanks for the offer ;-)
