Getting close to a source for f85r2

[pedestrian]

Now this is going to be a stretch, possibly offtopic, and wouldn't be worth mentioning even as speculation except in the present context of the handwriting at top of pages - in this case You are not allowed to view links. Register or Login to view. - and a Zolfingen connection.

There's plenty of speculation about the text at the top of f17r in threads like You are not allowed to view links. Register or Login to view..

There's some idea that it might be an instruction to paint something, "Malen [something] ..."

The second word looks like "aller", which might well be how the writer heard "alle" in a similar way he rendered "Malen" phonetically. But what is "aller"/"alle"?

In the area around Zolfingen, in the local Schwyzerdütsch, "alle" means "jeweils".

This might make further sense of a sentence starting "Malen" - Malen alle... / Malen jeweils... Paint each... / paint respectively...

If that's getting closer to what is written on You are not allowed to view links. Register or Login to view. (and the dialect boundaries and usage haven't changed significantly since the fifteenth century, admittedly another big if...), then it might contribute to the geographical origin question. 

Here's a interesting resource, mapping some Swiss German dialect word and grammar variants:
