Thanks, Russ.
Probably, I haven't clearly written. The building "Vodka distillery" is on crossing the Donskay street (later street Parhomenko) and the Kubanskay street. This place is 660 meters on the southeast from a building specified in the book and at your forum.
The building described Wigand Wuster, is often mentioned in other memoirs. I would like to find out this question for myself.
Thanks, all.
