The number plate is not originally mounted, every year the bikes got a new number after the owner had paid a year-tax.
The Todtenhöfer label on rear fender is only frame, no wheels, maybe there is only the fender from Todtenhöfer, I will check it. Also sometimes we find some unknown frames with serial numbers XXXXX (five numbers) and it is always hard to find out who has made it, perhaps now we can find some Masovias among them.
One more thing - about the Kilometerzähler on Your bike - I was wrong, it is not soviet production, it only looks like the soviet one (the lion or what animals picture/logo, this is not soviet, perhaps it is original).

Ok, thank you very much again for the informations! Yes, Masovia numbers are mostly 5 numbers (XXXXX), only from 1943 onwards they went to 6 digits. And all Masovia bikes I have seen so far, always have the same "Steuerkopf"

You mean this "Kilometerzähler":


I don't know if it is original. Maybe someone here has seen it before? EDIT: It is a Loewe Kilometerzähler from Germany.
