In the (possibly hopeless ) hope of clarification, here's what I have. Unfortunately, I failed to document the grade of some guns, or the source of the images.

PLEASE correct (based on a Research letter or frame stamp) and add the DOM is possible.

The No. 1 was introduced in 1890 and should not have the point on the top of the frame, nor engraving on the breech balls. There were very simple embellishments at the front, top corner and back of the lockplate.

As we'll see with the No. 2 and No. 3 patterns, things changed however from early to late.

I think this is Craig's 10g and an early No. 1 with the American scroll/nautilus pattern; note nothing on the breech ball. I don't have the DOM



Another 10g and similar; also no DOM



Probably a later No. 1 without the added engraving around the pins



Later with a simple floral pattern
