Intro to the Parker Gun...

I made a copy of the article to read at my leisure. I've read it twice now. Outstandingly helpful in it's simplicity, and although it can be a exhaustive learning process and subject, it is a fine roadmap for beginners. Hosford and Co. barrel wall thickness gauge may be an eye opener for some more weathered and experienced folk here, but for a beginner it may well be a tool worth remembering and obtaining. Tools that add value are never liabilities.

Once again thank you Robin Lewis!
