Chassis components all used British Cycle thread ( BSCYC), some threads into engine aluminium castings will be BSW, but there should not be any BSW,BSF or Metric, but maybe some BA in electrical components

You won't find many BSW on the frame, they tend to use to a course thread like whitworth into alloy like the engine to give it some strength.
If a bolt goes through several sections so for example maybe 1/2" is hidden it's good practice to use a bolt and not a setscrew. A bolt has an unthreaded shoulder and a setscrew is threaded all the way down. Wheels hubs and brakes and engine parts into steel sometimes use  BSCY thread and I think there are two choices in that. The rest of the frame if it's nuts and bolts you could use either BSCY or BSF. It's also good practice to not leave loads sticking through the nut so with a flat and Spring washer fitted leave half the thickness of the nut sticking through and file the end of the bolt to give a smooth edge.
Then you have a choice of normal or Stainless. I suspect they would not have used stainless but it has the quality of not rusting.
Some people use metric but I just can't do that even if it won't be seen.
Maybe not exact but should give you an idea.
