We don't "know" his gun, 56867, is one of the 69 28-inch barrel 10-gauge quality 2 Parker Bros. hammerless guns recorded in
The Parker Story. We "know" the records show there were 69 28-inch barrel quality 2 10-gauges.
Typing in the serial number 56867 on the research letter page at the PGCA web site reveals they do have records on that serial number --
http://parkerguns.org/ The PGCA has records both from the "Stock Books" and the "Order Books" while the published Parker serialization book was produced from only one of those sets of books, I don't remember which right now.
On most Parker Bros. doubles the rib matting stops about 1/16 to 1/8 inch short of the end of the barrels on unmolested guns. If the rib matting extends to the very muzzle that is a good indictaion the barrels may have been cut.
