OK, I've been looking on ebay and have found a few TC Hawkins stocks with sidelock and all parts without the barrel. They say the barrel inlet is 15\16 inch. Now as I understand it, the Seneca was 15\16 and the standard Hawkins was 1" barrel. Am I wrong? The Seneca 45 cal is what I want to get . What is the difference. I want the lighter gun. I want the .45 Cal. Did they make a regular Hawkin in .45 Cal. Do they know what they have on ebay? Please give me some help, and if anyone out there knows of a website that can help me please include it here.
