[Competition] Best folio number parallels.

[nablator]

Are some features rare or typical for a certain time/region?

I believe I have seen them in German or Austrian late 15th century manuscripts. I will try to find samples.

The date of the foliation can be difficult to know, but sometimes one of the owners wrote his name and year and his handwriting/ink matches the numbers.

So I'm searching "Sammelhandschrift" + "Besitzvermerk" in particular.
