Thanks everyone for the meeting. I enjoyed very very much, thanks for all the support and the kind words about my book.
The developer I mentioned is Ansco 130, sold by Photographer's Formulary as their "130 Paper Developer" (click here for link to the sales page). There are a few good and long-running discussions of this developer on APUG. Click here for one of the sticky threads on the subject.
I look forward to meeting you again some time in the future, sooner than later. Let me know if anyone needs assistance with your own book.
