re: older Threadings for Fittings

We're working on an older[1940's] car that seems to have odd threadings on the Brake & Fuel Lines. This TATRA may have used WENTWORTH(or Whitworth) Std lines as TATRA used some UK parts in their cars.
Typicall a car of this type was all metric(SAE). Is there a site/shoppe that sells these older type lines?

p.s. all I could find were the tools @ http://www.britishtool.com/fast.htm

Technical spec for Whitworth screw threads:

These guys sell them:

If you do a Google search with "Whitworth" and "threads" as keywords, you'll find plenty more.:)
