Sounds like a modern imitation of this book:
Henley's Twentieth Century Book of Formulas, Processes and Trade Secrets
1942 Revised and Enlarged Edition
The Norman W. Henley Publishing Company
17-19 W. 45th St.
New York
Copyright 1937, 1934, 1933, 1931, 1927, 1924, 1916, 1914, 1913, 1912 and 1907
Does your book include sections about explosives and pyrotechnics? Mine does. It has 861 pages not including the index.
