IBM model F XT barrel measurements

[PlacaFromHell]

Hello guys. I want to experiment a bit with the model F (nothing serious, just play arround with a custom plate design). I have barrells from an XT with a broken PCB but unfortunately my measuring tools are a crap. Do someone have an schematic of it or at least a good measurement of the barrel itself and the dot, with the distance between them?
