I collect, buy, sell & repair vintage dunhill Rollagas lighters. All the lighters I sell have been professionally cleaned, serviced with new seals (including the tiny inner seal of the needle valve). I also sell service kits for vintage Rollagases. The kits include easy to read very descriptive instructions as well as a high quality schematics of the Rollagas with numbered lighter parts. I offer personal assistance through messages, emails or phone calls to those who need additional insturctions on servicing their lighters or operating their recently purchased lighters. I am always happy to personally assist my customers.
