Right, a bit of a mystery to solve here. These images are from scanned slides, possibly taken at some time in the 1980's. Can you spot anyone you recognize? Know who the teams were? Was this your team? Or can you see anything that pinpoints the date? Do let me know.

Rugby goal posts in this one. So was the other field used for rounders at that time? A bit further out. But can you spot anyone? Fewer players. Know who this team was?
