A very good resource for the Talbot-era Sunbeams is Peter and Karen Woodall from Ridgefield, Washington. They have an exquisitely restored 1951 red Talbot 90 convertible along with an equally impressive 1953 Alpine. You can see a picture of this car on my Hillman website, where it was a shown as a 4-seat upscale cousin of the Hillman at our recent Hillman gathering: www.brigadoon.com/~craigb/hillman/gathering.html (featured in second photo down)
The Woodalls also have several other Talbot-era Sunbeams in various stages of restoration. Peter and Karen are true Sunbeam enthusiasts. They even drove their white '53 Alpine in our local North Bend Alpine Days parade, having motored 175 miles to be a part of the 6 block procession.
They will be on the internet soon, they reassure me, but for now, you'll have to contact them via post or tele. 360-576-4969. They're great folks to talk to about Sunbeams and Peter can help source some hard to find parts for you.
