Johnmac, I see you are a 'forum member' and not a PGCA Member so please accept this advice.
To begin with I would suggest you go directly to our "PGCA Home" page and click on the FAQ (frequently asked questions) and thoroughly read all of them but especially those that reference identification of Parkers and the various designs of actions and features.
Next, I would suggest you buy a book or two... or three, or four which have been written by Parker Gun 'experts' of their time so you can begin to understand how much there really is to learn about these wonderful old guns. Most of us are still learning about them and will likely continue to learn until the day we die.
The answers to your questions are really very complex and we invite you along with the rest of us in the process of learning.
Please consider joining the PGCA. It is only $40 annually and the benefits are many.
