G'day Chris and welcome
My mob are from Brum, not far from Selly Oak, the history of Scrambles and the ISDT interests me greatly as well as Speedway, in fact I was reading, just the other day, a four page early history of Greeves, in an OZ Classic magazine, Brian Stonebridge's efforts on the 197cc Greeves against the likes of Banks, Draper, Curtis etc , on their 500s was certainly a David and Goliath effort and marked a turning point in two stroke development.
