Hal, There are as many names for differing varieties of scroll as there are engravers and engraving collectors, but I will do what little I can to share some of the knowledge I have gleaned from others through thirty odd years of studying ornament and its history to put names that I would use on the styles in the following photos..
Acanthus on a Manton in crossed chisles hands circa 1819:
Acanthus by Harry Kell:
Acanthus with multi color gold inlay by Ken Hunt circa 1954, RH lockplate:
Acanthus with multi color gold inlay by Lynton S.M. MacKenzie circa 1970,LH lockplate:
Ken's work on the upper lockplate exhibits a celtic influence in the perforated ribbon incorporated in the scroll stem.

English scroll on a Kavanagh, some may call this large scroll in the context of English style.
Boss rose and scroll, or bouquet and scroll with running scroll border by Barry Lee Hands for a David Trevallion restoration:
I would call this an open vine scroll, it is an Acanthus variation. I would like to hear Smallbore’s opinion of the proper term and date for this style:
And this is more of the same, on a Westley Richards?
Acanthus with clamshell terminus and Celtic rope border:
Well worn Birmingham English scroll with open scroll elements, running scroll lockplate border and open vine with rose bud action border:
