I've been chasing, for some time now, a Victa utility base which has the fuel tank mounted on the handle bars. I think they called them the "utility pro" or something.
Preferably in the full crank version. The condition I'm not too fussed about, as in I don't care about rust, dirt, engine, no engine but having a working fuel tank would be ideal.
I've attached some pictures to help jog the memory.
