Need to replace a couple of the oil feed pipes on the model 9 and would appreciate it if someone could tell me the original size of the copper pipe I need and the solder nipple size? I presume all of the pipes from and to the oil tank are the same size?
Appreciate your help

Suspect this is what you are looking for:

Many thanks Daniel, sorry I missed those on the shop.

Just for the record, the pipes are 5/ 16" outside diameter (not 8mm central heating pipe which is slightly bigger and may no fit the olives) and the nuts are 1/ 4 BSP. People often suggest silver solder for strength - some original pipes were done that way - but soft solder is adequate as well as needing much less heat making it easier to do and also much simpler to de-solder and salvage old nipples.
And as a final thought, modern bright nickel plating seems to make pipes very brittle in a way that originals are not, possibly because the plating is too thick, not sure - but I don't remember having any bother with electroless nickel plate on pipes. Anyway if you choose to plate them make sure the bends are correct before getting them done.

Yes, nickel plating the pipes needs correct bending before applying. Nickel is very brittle not because of the thickness but because of the material itself. The reason is its face-centered cubic crystal structure in contrast to body-centered cubic of chrome which makes the latter hard (same as carbon vs. diamond). Because of the price I opted for nickel (not for diamonds) and it's ok.
