damaged BKA

[Zeller]

Hello,
I've posted this before on another forum a few years ago and the answers I got were pretty generic.
All the major details which could ID a real one from a fake are on the missing part so people tended to icon13.gif
There were few members who rightly pointed out that the cracks and the damage look authentic and not artificially made (with ice, acid or other tricks). Others told me that the hook (not sure if that is the correct word in english) of the clasp is correct as well. I did not dig it myself so It is in the grey zone, but I must say I like it. It was allegely found in Germany before I got it.
Any opinions,theories, explanations are welcome
Matt
