I bought a Yunker 3 earlier this year on either Gunst*r or Guntr@der, which had very little previous use. It still had the original magazine instruction booklet, spare seals and a cleaning kit in the stock. Not cheap but a very satisfying purchase.
I'd keep an eye on both sites as they do occasionally crop up.
Good luck with your search.

Currently looking for Baikal Makarov pistols with the following prefixes to the serial number: 98, T01, T09, T21, T22
Prefer boxed or cased but will consider loose examples too.
