I picked up a box'o'books from an auction from
a ham who went "silent key"
and the box had several handbooks, the 2nd oldest was a 1973. The oldest
was a 1949, IIRC. How old is "old" that you're talking about. I may have
one that 'fits the bill'...
I would think anything pre-1970 would do.
1949 would certainly have it.
