French Script by Monotype, a digital revival of a Stephenson Blake metal typeface created in 1905 as a version of the common French scripts of the nineteenth century.

Good comparison koeiekat. By chance I also chose _S_ for my detailed check.
Possibly both digital fonts were created by scanning a printed version. Alternately a conversion from a bitmap font from circa the 1990s.
The internal font info in the Tiara currently "in the wild" says the vendor is ATEC Page Technology Marketing. Inc.
Their website says "Since 1993, Page Technology Marketing, Inc. (PageTech) has specialized exclusively in HP® PCL® print-stream transformation, Intellifont® and TrueType™ Typeface font utilities and other related PCL technologies."

Anyway, both fonts are based on the old woodtype called Ironwood.
Ironwood is not identical with the letter shape but has well engineered outlines that could be modified to make a match.

The jump in the lhs stroke of _M_ and _S_, and in the rhs of _E_ is an error in the scanning process for the image.
