Yes, Haynes retired from being a pharmacist a number of years ago. I did e-mail Scott with Haynes' most recent address that I had as of about 2 - 3 years ago. He was selling whatever he had left but was not getting any extrusions re-run as the quantity and thus cost was prohibitive.
I am 76, and I believe Haynes was close to me in age. I first met him about 25 - 30 years ago at the Chicago March Meet 2 rail show.
