I just picked up a "Made in England" Raleigh Grand Prix, 23-1/2".

The frame is in descent shape and I plan on restoring the bike, i.e. repacking all of the bearings, aligning the frame and fork and re-building the wheels using ss spokes and possibly alloy rims.

I'm curious about the frame. Does anyone know the specifications/characteristics of the 2030 tubing that was used for the frame and forks, such as, seamed or seamless, wall thickness, strength vs. weight, etc.?

Was the tubing used exclusively by Raleigh or was it available to other manufacturers?

Any information about the manufacturing process, lugwork, etc. would also be helpful.
