Hello, please i would like to know your opinion about: i have an old 1970 Dunhill Rollagas gold lighter. Its not used since 40 years almost, but it is in pretty good shape. Would you send it to dunhill official repair center (that would be like 200 dollars in total, including the instalation of pipeflame and 6 months warranty)? Or would you just take a new brand IM Corona Old boy? Thank you very much for your help!!
