You've got a few options open to you when it comes to selling. You could try placing a traditional 'for sale' advert in classic car newspapers and magazines. Or you could place an advert online in the classifieds of classic car website. There's always internet auction site eBay or you could take them to an autojumble. And, as you've already mentioned, you could contact the clubs to see if they want them for their spares operation (or know of a club member who needs them). Some of these options are free, others will charge, while sites like eBay will take a cut of the sales price. As for the value of the items - it depends entirely on their condition, but I think you'd be looking at about £10 - £15 each.
