The only references i can find on the web are about welding rod substitution options that also seem to indicate it could be magnesium based? Any links to better spec or description of the actual material?
thanks!

People did not use to like welding. Even as recently as the late sixties, early seventies the Brits would go to great lengths to avoid a welded motorcycle frame.Although much more complex that welding, perhaps it was faster to batch mating tube components and brackets?
Stephen, got a question about a note in the original drawing. "Holes in tube and plate reamed in situ" How on Earth did they keep the washer/plate and crush tube from simply spinning driven by the reamer?
And also wondered if the note was a shorthand for "everybody knows how this is done" just to distinguish it from another instance that required nothing special.
I'll bet you are correct.
The tubes probably arrived already reamed. Afterall, there is no advantage to ream those in place.
The other pieces must have been for the "ferules" to properly do their job. Perhpas the (pre-reamed) tube might have helped guide the reamer to the "offside" hole a little, as well.
