This brief letter is neither intended to demean a writer or a particular gun, but serves as a great instructional tool for beginners. First, some restocks are very well done and hard to discern from an original. Other restocks, either done during the the period of use, or later on, are very obvious.
One blatant restock sporting a Dickert barrel which I handled when it appeared on the "for sale" wall of a noted Lancaster collector over a decade ago can be found photographed in Whisker and Wood's Armsmakers of Lancaster County, PA., page 83. The fact that a really righteous Dickert appears on pp. 84-85, and another acceptable one appears on p. 82 makes for easy comparison. Since you may not have the book available, I'll give details of my line of thought.
First, the rifle in question, captioned as "Jacob Dickert, a pre-Revolutionary War rifle." The following red flags appear. First, the architecture differs substantially from a classic Dickert as seen on the next pages. Not even close, and, take this from me, it is thinner in width, which you can't see in the photos. Next, and very blatant, is the lack of two crossbolts fastening down the lock. Look at all the other Dickert examples...they were made as flintlocks, the only technology of the era. This appears to be a total restock of an old Dickert barrel, made into a percussion gun, with all new wood used at the time of the rebuild.
Now to the triggerguard. I submit that the Dickert shop would have removed more metal and done a neater job on it, and anyone in that shop would have known how to install one correctly, not with a wood screw from the bottom and no inletting at the rear. Compare to the others.
Then there is the patchbox. Not likely. Look at all the others. They are 4-piece boxes of classic Lancaster design (Dickert helped establish this county characteristic). Also note that Dickert often used a lip at the front of each patchbox sideplate that tightens it down under the pin hinge instead of using a third screw in the front to fasten it to the stock. This basic, 2-piece box is not even representatlve of Lancaster, let alone any particular shop.
The lock is a later one marked "Warranted." And the lock-bolt plate with the "fairy wings" and single bolt is common on later guns around here.
Please don't tell me that it could have been an apprentice. They were trained consistent with shop standards, and anyone who did this kind of work in that shop would have been given a swift kick in the butt and handed a broom.
I submit that the only thing Dickert may have touched on this gun is the barrel. I would agree that the job has some age on it. Those two white spots on the wrist are filled-in worm holes, and, if I recall correctly, they come out in the patch box cavity. Yet, this is no "pre-Rev War rifle," not by a long shot.
