Yeah, I probably got 'em switched around.
CVA's Hawken pistol had brass furniture, a 9 3/4" barrel and a flat on the bottom of the grip (just looked at the one on the cover of the Black Powder Digest 3rd ed. 1982). Inside they have a b&w pic of a Mountain pistol - 9" barrel, German silver furniture and a rounded grip bottom. My gun (pictured) has a 9" barrel and you can see the furniture and grip shape.
The rifle pics in the book with the Mountain Rifle caption clearly shows a two-tenon barrel and the text says it has a 32" barrel with silver furniture. They don't show a picture of the CVA Hawken rifle but the text says it has a 28" barrel with brass furniture, which fits my rifle.
I guess I was kinda holding out for the fact that the original Hawkens had iron, not brass fittings, so I just assumed the CVA rifle with brass fittings was a Mountain Rifle like the box said. Clearly the box was wrong and so was I.
Now I gotta go change all those picture captions...
