Norton ES2 barn find. Will it start after 34 years?

This '54 Norton ES2 was one I bought with 3 others last Christmas. The tax disc on the fork leg was from 1986 and the seller confirmed that was when the bike was last on the road. The others were a '61 AJS that was seized, a little Greeves trials bike that opens this short video and a Honda CB 72 from 1961. All were very dirty, on flat tyres and totally buried under domestic junk..old lawn mowers, bicycles, garden furniture, piled to the roof in this guy's shed. They had however been kept totally dry. I've never been a great fan of British iron but the Norton intrigued me and I hoped I could bring it back to life without too much sweat and expense. This was one off my first attempts at filming so please forgive the clunky presentation, the portrait shooting, the hesitations-and the flat cap, but the Norton is the star here and I hope you'll enjoy the story. If you've any old bikes from the 60s or 70s and think they'd make a good subject for a vid, or you'd like to sell, please email me on [email protected] and I'll get back to you. Thanks, Rod
