[LAVAMAN-UK]

Hi All,

Just managed to get hold of this lamp off e-bay. Hasn't arrived yet. Im sure it looks like an old Crestworth lamp. There was no info on the listing. Could anyone give me some info on it?

Cheers in advance!!

looks like a pre-mathmos Jet, probably best to wait for a better judgment though, just thought I would try to shed some light for you!
