Kudos indeed to Mark Conrad and his crew at our research department. I recently bought a PH 16- 0 frame 26" Twist barrels- sn 133556. I sent in the form and my check (best $40.00 I have yet spent on gun "pedigree") as I wanted to verify the 26" barrel length. All the criteria I have learned seemed to support they were the original factory length, the research letter is "Proof Positive" I had guessed 1906- It shipped from Meriden on July 29th 1908 to Edwards and Walker Co. in Portland ME-- Who ever owned it before it came into my custody took very good care indeed.
Also thanks to PGCA member Harry Collins for his great assistance in helping me with the replacement top lever spring- Gun functions perfectly with snap caps, and when you remove the forearm there is NO wiggle at all from barrel to breech- truly an "Olde Reliable"- and with short RST loads- a great addition.
My friend has a 20 Trojan, O frame of course and with 26" original barrels, a Ilion series with a single trigger, and we don't have Postal scales, but my PH seems to weigh a tad less than his 20- both have that perfect balance and in hands feel of Parkers-
