First of all, thanks to both Bruce Day and Dean Romig for your quick replies, and thank you to the PGCA, for this forum venue which allows a want-to-be member like myself to learn and better appreciate such a fine firearms history as "The Parker Gun". I look forward to joining the PGCA as soon as my economic situation improves.
The measurement of the distance from pin-center to pin-center, is 1 1/8".
By the way, does everyone fall in love with these guns?? The more I look at it, and research Parker guns, the tougher the idea of parting with it.
