Excellent - good luck and don't forget to post pix of it working properly It will be interesting to see if that soves your issue. It is also really nice to have a bit of working family history
Well, new gaskets (thanks for the recommendation) and another new wick and now lights and stays alight !. Don't know which works but very happy. Many thanks Grandad was a pit deputy so I believe this lamp was used by him but like a lot of other miners he has not been around for a long time to ask. Thanks again.
