No blueprints on the engine or any of its parts. Nothing on the clutch assembly. I remember blue prints of pulleys, hubs, rear sheave, not much that I thought would have been there. Bummer! I talked to the guy that controls the archives. The collection came from Wollard's wife when he passed. The guy I talked with thought there should be more info since the bikes were manufactured right there in New Orleans. I wanted to see production numbers, serial numbers, and technical info, but it just wasn't there. He even put out feelers to the biker community, old timers, and everyone else he knew in the area, he was a bike guy too, for more info to build the data base larger. Zip! Nada! No responses. He was surprised also. Our site has more info than the university. I guess no one thought this info was valuable through the years. I'm glad I was only 2 hours away from New Orleans when I decided to check it out. I've wanted to go there for info for a long time. I had great expectations of a stash of valuable info on the Simplex. But I tried. Wasn't a total failure, buy not what I was hoping for. Bob
