Can't read the adobe thing to research a 16 PH

[Old and Reliable]

I just acquired a 16 PH with 26 inch Twist barrels in VG condition- SN is 133556. When I tried to enter this data I get a pop-up blocker, so I don't know if this gun will be "lettered" or not- WK stamps all numbers match, barrels are uncut, no dents and bores shiny with no fouling- 3 lb. 8 oz. stamped weight with WK in oval- forearm iron only has sn- the outer latch is engraved PAT'D MAR. 26, 1878- water table right barrel side- PAT'D JAN 18 AUG 18 1887 May 7 Oct 8 1889 PAT'D AUG 15 1905- letter grade stamp is P (no number stamp - PH guns were grade No. 1, right?? then sn 133556- last three digits on bottom of trigger plate as seen from the lug opening, also on back edge of barrel lug, and it has the 12.5% pinned wear plate- 14.25 LOP to older spurred DHBP with engraved screw heads, pg with original cap and screw-- any info from the Brethern here would be appreciated- Thanks- FM
