Hi, I am looking for help in finding Information such as old brewing logs and records for brewing pre-prohibition and beers from the 1940 - 1970. I have been brewing off and on for over 40 years and recently I have concentrated on brewing these types of beers. I did find a beer blog that was very interesting and useful (Oshkosh Beer), but that's about it. I am particularly interested in the details of the mashing and other information of this type.
