Can anyone point me in the right direction for a new top to suit a Petromax 821 baby. I see this poor old thing for sale (or almost give away). A new glass and knob can be bought from the Petromax website fairly cheaply, a new hat might be more difficult to find. There is already one baby in my collection, unfortunately with a badly cracked fount. Hopefully I will get one good one out of the pair. Even better to get them both working again.
