These are the unique photos which were made in the city of Kurgan, Russian Empire in the mid 1890s. They show traditional Russian folkstyle wrestling competition which was an essential part of the feast of Pentecost celebrations.
The proper Russian name of this style was wrestling "na opoyaskax", which is basically a collar and waistband fixed hold style of wrestling with tripping being allowed.
Most commonly utilized techniques were: outside stroke, back-heel (both from outside and inside the legs of opponent), buttock and cross-buttock. First down loses the fall. To win the wrestler has to throw his opponent 3 times.
Modern times, the revival of the sport of old in the city of Kurgan.
You're description of the ball games is 100% accurate Peter 😀 apart from the ale guzzling at the end of the match and sometimes during 😀 I'm not sure about Scotland but the Shrove Tuesday ball games are a feature of England and also Wales. Ahterstone is burial place of the first King Arthur, hence the name "Arthur's Stone."
