Johnny Chamberlain was also 4' 9". Jerzy Kowalski was another under 5 feet, I know, and so was Sam Nikolajsen.
Obviously, there have been plenty of "short" riders, but I'm not sure how many have been exceptionally short (5' or less).
I admit that you probably aren't as weird and warped as I am (very few are - or at least, few would admit that), but don't sell yourself short, Steve! You have a vast knowledge of riders over a long period of time, so all you have to do is think of the names!
I know the junior matches were introduced in the late 80's, but even so, I still considered them a "second half". I honestly can't remember exactly when we lost the "traditional" events (I'm getting old), so maybe it was even in the 80's?
Early to mid 90's I believe. Cant be any more precise than that, as I emigrated in 1990. They had moved up from 13-heat matches, so they didn't want to bother with a second-half.
A lot of fans thought they were pointless, but there are still a few of us on here who miss them...
