The Andys can still be found.I have some vintage non-automobile tools and have found several web sites with excellent resources, and knowledgeable people.
The Old Wood Working Machinery - owwm.org and owwm.com
They have added Old Metal working machinery to there index.
SMOKSTAK -
http://www.smokstak.com/"Antique engine forums related to collecting, restoring and showing hit and miss engines, vintage Diesel, steam engines, antique tractors, old generators, pumps, industrial antiques and collectibles. There are thousands of old engine photos and thousands of discussions about all types of engines and old iron topics." They were very helpful with my Onan.
I also subscribe to a machinist newsletter there forums are better.
