Parker Grade 0 Top Lever 12 ga Hammer gun, SN46491 with 28" Twist barrels bored modified both.  Number 1 frame - weight 6 lbs 14 oz. Good coundition with traces of original case colors. Good solid wood with most original varnish and some minor scratches and a small gouge on right side - dog's head butt plate. Good barrel pattern.  Locks up tight and has slightly rough bores but no dents. I have been shooting 1 oz 8000 psi loads in it. PGCA research extracted from Parker factory records provide proof that its current configuration is factory original. "The gun in the stock book was completed 11/1885 and was a gtade 0 twelve bore with 30" barrels. The order calls for a 28" gun with cyl chokes. It was shipped 3 days after the order came on March 18, 1886, so I suspect they cut the barrels back to 28". The order book also calls for a 13 1/4" lop. So they cut the stock back as well".
