Did a bit of work on the images Bruce. It should be a C grade and Remington called that pattern Washington N.3 B.P. It was also called 'American Flag Bunting' and 'Stars and Stripes', and was quite popular with other U.S. makers, esp. Ithaca but for some reason not Hunter Arms.

We know from Claude Gaier's
Four Centuries of Liege Gunmaking that Ernest Heuse-Lemoine of Nessonvaux named both "Washington" and "Boston" patterns for the US market. The 'rough forged tubes' were paired, wired together, and shipped to Ilion in a barrel. The pattern is very hard to identify on the rough tube, and I suspect the fellas at Remington were none too happy after joining, finishing, fitting, and staining the barrels to find the mismatched segments
And the breech is a mess!
