Hi Gene, thanks for that info. Where the lack of a serial number applies to a rook rifle, or big bore shotgun, I,ll leave them out. Experience has taught me, however, that early pinfires and hammer shotguns often lack a "discernible" serial number due to wear and tear over the years. It,s very frustrating, Same applies to name on the rib. Often, this is lost due to re-browning, or blueing, or just over-enthusiastic cleaning, with the wrong materials!
Back to the drawing board! I have found some more examples, in a small number of catalogs from Evans & Partridge, Hampshire. These are late 90,s to 2002, so you again may have them listed. I shall then plough through a number of small regional auction catalogs, when they are exhausted, it,s back to the early 70,s, with Weller & Dufty catalogs.

Regards
