Different butt stock and grip cap

[Pa SxS]

My apologies to Mr. Jones, it is listed in the Order Book as a DH. It's within a few thousands of the earliest hammerless guns. Mr. Dudley nailed it as a very early hammerless gun. The question is is this gun's engraving pattern the same for all these early DH hammerless guns, if so, when did the change to the pattern we are used to seeing on DH's happen? I wonder what a GH or PH in the same serial number range would look like? Let's see some closeups of the 3 sides of the receiver. If the engraving pattern was different, could it also be that Parker didn't put the cheek drop points on either at this early time? I think the stock is original.

We don't have the Stock Book for this gun but we do have the Order Book. The info is worth a letter.
