Bottled gas heater case, no gas, needs new adapter (Seafield EH7)

This has been a great heater but you can't get gas bottles to fit the adapter any more. It has an old Mac-Gas adapter, needs a new-style Flo-Gas one (or similar). You will need to buy a suitable gas bottle, first one is likely to cost around £100 but refills are cheaper. Case is stained and a bit battered but functional. It's heavy and bulky so we are replacing it with a different type of heater. Pick up most mornings or other times by arrangement.
