It could well be a 2, looking at this:

Not a scholar either, but a quick web search turned up this [1].

C2 seems to be "Lesser Mode Imperfect, with Imperfect Time".

I would suggest using "timesig.C44" as it stylistically matches the
number two from Emmentaler. Otherwise, use a two from some other font
to match mensural C.
To match the alignment, you need to use \vcenter. Consider:
%%%%
\override Score.TimeSignature.stencil =
#(lambda (grob)
(grob-interpret-markup grob #{
\markup {
\musicglyph "timesig.C44"
\vcenter \number 2
} #}))
%%%%
