I appreciate the response Saxon. For titles & challengers, I'm looking for a clipping of this: https://wrestlingheritage.co.uk/a-year-of-wrestling-1946/
"The December 1946 issue of The Mat magazine (published before the deliberations of the Board) listed the champions and challengers as follows.​

I'm not sure if these are the same weight cutoffs mentioned in the Blue Blood book.
