Cecil, the Armstrong car was supposedly a mule car that was used to test the new 409 engine. Story goes that the car had A/C to test the cooling ability of the new motor. The car also had an additional cowl tag that no one has ever decoded. I saw the car at auction a few years ago in Hershey, Robert Street and I attended the auction and I bid on the car, I had no intention of buying the car unless there was no one else present that knew what the car was. The car was not advertised as being anything other than a 61 409. Verne was still living then and I called him and verified the vin. Someone did get a steal, the car sold for 105k, I bid it to a 100k , there was one other person at the auction that apparently knew what the car was because everyone but he and I dropped out at about 70k, each time I would bid he would up me 5k. I watched the car being loaded the next morning, new saw it again, have no idea who bought it or where it went. I have some photos that I took of the car that I will post, got find them
