[CE U 13.1] Fonts in Models - How to find "Missing" ones

When I open a .cel file, I'm greeted by the following message:

File ...\Organization\cell\SRS_ToolCells.cel could not find TrueType font [SRS TT]. Replaced missing TrueType font [SRS TT] with [Arial]. Some text may not display correctly. Make sure that the appropriate True Type font file (*.ttf) is installed on the system, or in a directory specified in MS_FONTPATH.

I am attempting to find where that font may be used (in which cell model). I run this bit of VBA code:

Sub DumpFontsInDesignFile()
    Dim oFont As Font
    Do
        Set oFont = ActiveDesignFile.Fonts.Find(msdFontTypeWindowsTrueType, "*SRS*", oFont)
        If oFont Is Nothing Then Exit Do
        Debug.Print oFont.Name
    Loop
End Sub

and the output does not include "SRS TT". So, where may it be hiding and how would I find the occurrences?

Interestingly, when I use only a wildcard for the Find(msdFontTypeWindowsTrueType, "*", oFont), I (seem to) get all the fonts in the active design file (?) and the missing "SRS TT" is NOT in that list either.
