I attempt to show here what I think Karen McDonald saw. I'm sure sure Karen can put it better.

I'll try.
The writer doesn't normally curl the top of a "b" downwards, which is why I see the tail of an "f" touching the "b" (the 3rd letter).
If you cover the main part of the word, the superscript looks like "fld.". (I think!

The serif on the top of the 2nd letter is also uncharacteristic for a "b" from his pen - it looks like a correction to me. Whether it is an "r" or not is a question which remains to be answered.
An "e" would be less likely, though.
I do agree with Roger/despair, though: I would also have said "in" for a town.

Unless I was talking about an event in a town, e.g. The Arborfield Country Fair - then I would say "at". (I hope this makes sense...)
