The OP hasn't posted for about two years.
Having said that, there are a handful of members who are either retired Bell System employees or avid hobbyists who are very knowledgeable of 1A2 key systems. If you have specific questions, browse the existing topics to see if the questions have been previously asked.
If they haven't, feel free to open new topics and ask away.
We do ask that tacking onto old topics be avoided. New topics can be opened and links to old topics incorporated.
