Great those old books.
Topics are quite often very well explained and good schematics are provided too sometimes.
Amazing how the technical Swedish is reasonable understandable as well.
I like the old Hawkins Electrical guide, second edition 1921. and Audells new Electric library 1929 which I bought the complete series off for about 40$NZ. 27$US
total 20 books!! outside of the pages are covered in gold.
Second hand bookshops are the best places to source these old books if one is interested.
