Please take a look at image [b]mv01[/b], that’s a legit ‘YV’ version used by [i]Müller[/i] from [i]Volkstedt[/i] (here including the matching genuine item number). It’s ‘Y’ (instead of an ‘M’) form comes from an unlucky print, just like the ‘V’ often looks more like a ‘Z’:

Image [b]mv02[/b] shows a legit ‘MV’ used from 1930 up to the factory re-location in 1962. This is the most common German mark type found:

Image [b]mv03[/b] on the other hand shows a mark type I dubbed the ‘crazy kid’ version as it looks as if some small kid made it. Even the writing does not appear “naturally written” but rather copied line-by-line from a note.

All of these basic types do not match the “style” of the mark included on OPs piece, therefore I doubt the figure is a genuine [i]Müller, Volkstedt[/i] or [i]Johanna Saar, Seedorf.[/i] item. It could (with both eyes near closed) be pushed into the direction of the later [i]Saar[/i] kitsch editions made in Dromcolliher (Dromcollogher to the locals), Ireland. But seeing the style differences that would be really hard to believe.
