Brakeline Material anf fittings query

[Nellie 1]

Guy's

I am just in the process of refurbishing some of the chassis components and one of these are all the brake lines with new flexi's at the end.

Can anyone confirm whether as standard the rigid lines to the brakes are either Copper or Cupra Nikel?

And if possible does anyone know the pipe diameter used and size of fittings.

Thanks in advance
