I'm not sure try
www.saac.com
The register is over 1000 or so pages with even more photos so possibly is not on line. It will be for sale soon. Not sure of the price.
You will see the email address there for Ned Scudder the keeper of all things good and the register. Perhaps he can advise.
Also Ron our Moderator may have a copy.
Sorry I'm a member of SAAC and perhaps should know. I did speak briefly with Ron at SAAC at Fontana Cal. He was taking lots or photos and documenting so he will possibly have an answer for a possible question
