Looks like from the 'graver walk' found on Vulcan grade Parker shotgun, an "embellished" and refinished Parker- what are the markings on the barrel top rib, and the grade mark found on the receiver flat, along with the SN-- No 1 frame is fairly common for 16 gauge Parker guns, sometimes you will come across a 16 on a O size frame-- More detailed photos would help us here- RWTF
