OWD,
I forgot 2 other Boswell guns:
12 hammer pigeon gun, 30" damascus, pitted bores, checkering worn smooth. The original case is in better shape than the gun. Bores are proofed 13/14, chambers are 2 1/2 12. There is room for honing. It is a best hammer pigeon, just shot to near death.
The other project is a very early Boswell 12 top-lever hammer, early wedge forend, non-rebounding back action gun. It has the same early address the 10 hammer has (Edmond St). The SN is in the 2xxx range. It has badly blued damascus barrels and pits you wouldn't drive a 4x4 through.
The 10 bore, SN 7016, is really early, 32" bbls, 2 5/8 nitro. I think it is on an 8 bore frame as the fences are huge. I use it in Vintager 10 events. Patent marks date it to around 1878.
The 3 SLE's are 12290 sleeved, 2nd grade, 13030 sleeved 2nd grade, and 13330 Nitro damascus Best gun. Chris Batha has the records on 13330 for 1899. The other guns are earlier and those records are lost. I have looked at the locks of all 3 guns and they are totally different even though only 40 SNs apart. I guess Boswell sourced them from different outworkers.
The Bosell projects are guns whose barrels I'll use to learn how to brown. I have an E. Lang, Masu and Ithaca Crass all with nice Damascus patterns and badly pitted bores. I just need to finish moving and fitting out the vault workbenchs for projects.
Joe
