"you bought the object" did not translate well. I don't know what it means. I was reading another post and I wonder if it wouldn't be allowed by the administration to allow postings in two languages, for instance in this case I seem to read German better than the translating program.
I am at a bit of an impasse. I think you need to go to the Heraldik site and post the two wappen, and see if they can help.
The one with the crowns, is evidently that of the abbess, similar to a later one I found by searching " wappen abtissin Schanis" in google images. The other with the bears is evidently the Bellheim coat of arms. The problem is where did Anna come from.
If you google "von Bellheim zu Baumgarten" you get 6 references to her, but I could not find out which Baumgarten they were talking about. You might double check and read them.
Also
http://books.google.com/books?id=VD5SAA ... im&f=false which I had trouble reading, as it is old German spelling. It is odd that even I can spell German better than the engraver here:

It could of course be Baumgarten in the North of Germany, but that doesn't fit well with the South German nature of the convent. There was at least one Baumgarten in Austria. It seems likely that if she didn't order the items from the closest silversmith she might have had it made in her home town.
