My dad and uncle restore mostly Massey Ferguson stuff.
One thing I have gone to a few times is an old machinery show in Aiken, SC. It can be found at http://www.aikenfarmfest.com/
I have a ton of photos and video from the past couple I have gone to and will put them in some online protected gallery next year with all the other higher end stuff I have shot up.
The old machinery is so cool.....
There’s a farm heritage museum in the little town I grew up in. Our Independence day parade is primarily old tractors.
