Just a couple of notes on your pics Gos, and they are real fine too.
The blue TX500 belongs to a good mate, we rebuilt the motor just one week before we headed off to the ral from Bris, it didn't miss a beat, only the very first model had the head prob, the next one that came out was sorted, and that is the same deal with the TX750, they would froth the oil due to a small sump, the next model came out with a bigger sump and fixed the prob.
The bike you called a black bomber is not a bomber, it is a CB450K3, the bomber is the very early models with drum front brake, like the one with the maroon helmet on it, which happens to be my bike, and yes I rode that from bris too.
The CB500 twin belongs to a vjmc past president, he bought that new and it has never been restored, he just keeps it highly polished. Although about 50cc larger than my 450 bomber the 500 is slower due to gaining weight.
The 350/4 is pretty original except the colour, I have a red one in my garage, it is listed for sale at netbikes.
