Early Christmas gift It is marked on the tank as a Primus No 1050. The glass is also marked as Primus and looks original. Apart from the layer of corrosion, the main current issue is that all of the controls are seized. The hood comes off so I can remove gently remove the glass. Followed by soap and water and a little Autosol to play hunt the date code. Any suggestions on starting a more thorough dismantle (passing it on is not currently one of them ) ??
