You have to be an actual SACA member the recieve the Bulletin in the mail, I think its worth it. Stuff thats printed in the bulletin is way different than the forum.
This is the system with the Quartz control rod, I believe.
-edit-There was also the waterman system, one of the two, used a bronze expansion rod, I get this mixed up sometimes, Doble and White-
