This lighter is one I acquired in one of my sortees to Estate Sales, auctions etc. Well when I tried to fill it with butane it spewed out of the bottom. I saw these rebuild kits on ebay and messaged the guy with pictures of the Dunhill I had and if his kit would work on my lighter and if he had detailed instructions. Got a reply back and he said it would most definitely work with my lighter. The kit was only around $15,00. Received the kit and sat down and did the meticulous work of replacing gaskets, felt pad and these very small gaskets and spring in the gas control valve and the needle valve. He did give detailed instructions with an exploded view of the Dunhill and its parts. I now have a working Vintage with pat. no. Dunhill lighter, very pleased I am.
