JLJ, I've done quite a bit of searching for the specific strain of Rutgers that Red Baron is looking for and in one of the earliest posts here I suggested that he contact Gleckler Seedmen in OH b'c they were the last to list it many many years ago and the hope is that Adam's father George might still have some in storage.
Just my opinion but I don't think it will be possible to ID this specific Purdue one just by growing out Rutgers seeds that are not known to be the Purdue one and making a decision based on visual perception alone. Too much time and distance from when they were grown as was noted above.
