I have loved the B-Macks since I was a kid in grade school and a friends dad was in the trucking business. My Grandfather worked for Ward-Lafrance in Elmira, NY before I was born. IMO, this stuff is pure American history, and these specimens were a huge part of making modern day America. When you consider everything that was transported over the decades by these beautiful behemoths, it's no wonder we love them.
I had a client about ten years ago who was into restoring these Macks with his Dad. I should have gotten some pictures, I know. There is some fantastic vintage stuff on this thread.
