Not much in tins these days, but I can buy a reasonably large bottle of basic sewing machine oil at a place originally aimed for tools and car related stuff. These days they have sections for kitchen items, dogs/horse stuff, etc., and in the section for bikes there is a bottle of the basic oil, sewing machine / chain oil.
If you want larger containers of it, I guess it would be labled "pure acid free mineral oil", and thickness something like SAE 10.
The only thing worth ordering from the US would be TriFlow, I'm not sure who sells it in Europe. I can get Finish Line Ceramic Wet Lube in bike stores, it has teflon and perfect viscosity for sewing machines. You can easily find equivalents near you if you just go to the right store.
Drops of white spirit for sticky metal gears; various spray can stuff for much the same purpose; labeled something in the direction of anti-rust, tool-box on can, TF2 spray with teflon, WD-40, CRC 5-56, PB blaster,... For polishing up, Auto Glym Super resin polish, I guess most places in the UK have more stuff to choose from than my city. I recently noticed a UK seller on ebay who has a special carnauba based Featherweight polish, it will give a deeper shine than the resin liquid. The resin based polish tend to last longer.
