The original question is almost impossible to answer. The people who.might have experience in those years are not available for comment. There was an interesting TV series on bare knuckle boxing. A few women took part in this but it was regulated. The ladies, some from good background would hold coins in her fists. The first to drop them would lose. In the slum of the city, if two women clashed they would arrange to meet and word would quickly spread. The fights were without rules the the women would be at risk of infection from wounds in the filthy street.
Research shows these women were manly Irish immigrants and very poor. The gentry, both men and women, who dared enter these area, centred off Tottenham Court Road, would be treated to fights to the finish and the women would often fight topless so their meagre clothing wasn’t damaged. There was no evidence that women over 30 fought.
As Uk fight fan rightly say, the only fights we learn about are those that go to court. Local papers can be seen on line and although you don’t get a blow by blow account you get the ages, the reason and the place. A report of road rage in Bournemouth saw a women of 65 battling a woman in her 50s. The good thing was there were photos of both women as they left the court. No need for imagination.
