I have a small collection of Russian Zemstvos, and I have a 2004 catalogue by Gurevich, et al, which is pretty good - but it seems that most collectors refer to a catalogue by Karl Schmidt. My understanding is that his catalogue(s) were written in the 1930s and I have never seen one for sale. Yet so many dealers list their stamps using the Schmidt catalogue numbering.
Does anyone actually have one of these? Is there an online version available?
Thanks. I know about the Soloviev catalogue and I can get one, but am really looking for the Schmidt catalogues since they are so popular.
