I bought this recently for a fiver and I'm hoping to restore it without spending too much more! seals need replacing, new legs are needed and obviously the whole thing needs a polish. I thought I had a pump issue but last night fiddling it suddenly started getting pressure so I'm hoping it is ok. Not sure what the 10K stamp signifies. Is Esso Blue still available? I've been using Parasene not sure if that is the best... the pump has had a couple of washers added which perhaps means I need a new one. The pump tube all looks ok hope so as removing it might test my soldering skills.
