Well Peter, welcome to the site!
Close to a third of my shots are scanned in slides, and most of the remainders are scanned in photos, since I've only had digital for two years now. So I understand about the quality of the photo problem.
You've got some nice antiques and weird planes. Might I suggest before you get too many more posted that you sort them in some type of folder system, such as types? Makes it easier to look at and go back where I left off! You don't have to get quite as sorted as mine (I like my military sorted by types - I think it's easier that way), but just some organization like most posters do.
I am one who isn't so old (56) yet I have a couple VC10s I've seen:

I'll be looking forward to see what other stuff you have across the pond.
