Could that explain nearly 4mm sitting out?
No, mine is less than 0.5mm per side over the nominal length, so that's how far out the chainline/Q-factor would be.
I've mine here I only have a basic caliper to measure but if you send me how to measure I'll do it and post results :)
For an ISO spindle, the measurement should be 12.60mm across the flats measured 2mm inboard of the axle end (according to Sheldon Brown). You should be well onto the flats by then, I had to do some maths because my axle is short and chamfered too, and the JIS measurement is supposed to be 12.65mm at the very tip; at 51.5mm off centre on my "103mm" axle, I'd have been measuring air.
I've seen some horrible BB axles, Token are not among them
On my sample of one 103mm JIS axle, across-flats gauged at 12.750mm are all at least 50.5mm off centre, which would make the worst case nominal length about 103.9mm (the point at which the across flats dimension would the the JIS nominal 12.65mm if the axle actually extended that far). It's a bit big, but well within the range which could be swamped by variations in assembly.
