Exactly right, you almost have to be well connected to build such bikes as the parts just don't show up, it's not like putting an mx1000 and full wrap flights or even a DC hinge clamp on a build, try finding a cook clamp or even a PLME for under £300 and you'll be doing extremely well

And that's just for the mid to late 70s stuff, building something pre 75 is a whole new ball game entirely
