Yep, Andrey in Moscow as per Gairdner's link (Unuta77 or his "Balalaika store" on eBay), is the best purveyor of all fine Russian shaving bits. He sells Voshkod, Rapira, Lada etc, along with a natty line in Russian DE razors and some scary looking colognes. Postage is dear on the latter, otherwise it's reasonable prices. He does very good Russian sample packs, not a bad blade in sight.
Post normally takes around 7-10 days from Moscow and it's all tracked, I've ordered 3 times and found him reliable.
