Below you will find a list of Russian towns with assay offices at different times. However, please note that it turned out to be significantly more difficult task than I thought. Please note that the spelling of Russian transliterated names is a problem (always been...). In addition, different sources provide different and in some cases inconsistent information. Therefore is my list by no means complete. I would appreciate a discussion where this list would be discussed and corrected so that an as accurate as possible list would emerge (cannot hardly wait for you to comment...;.)))). It would benefit us all.
The bold text shows the missing towns.
