transformer core needs. This is a GREAT catalog. It covers all of the
earlier transformer lamination alloys right up to and including MuMetal
and 4750. There are very detailed processing and annealing instructions
in it. I'm talking actual step by step instructions. It is laid out in
beautiful art deco styling nicely done in full color; 34pp. Scanned
completely in color at very hi res preserving the stunning color
illustrations. As rare as rare gets and scanned from an immaculate
original. Contains much lamination and alloy info not found anywhere
