Out of dozens of photos of Russians playing Russian billiards throughout the Soviet era, none that I have seen showed chalk on the rail or being used. Ebay is overrun by sellers from Russia and Ukraine selling those awful Soviet-era cream colored ball sets. I have never seen a chalk mark on the cueball. Does anyone here have knowledge on this? I knew a Russian chalk collector who had never found old Russian chalk either. None of the surrounding countries seem to have used chalk either, except Bulgaria.
