I find my '71 Commando built in '70, as it does have nearly everything " '70 " related, square box oil tank, ring around headlight,tripletrees,frame, bolt-on rear hub, I often wondered why the center stand didn't reach the ground. (both tires are 4.10-19) and there's probably some other things not mentioned or I don't know. The only thing I've come accrossed with the Dunstall is that it takes the 6ca points rather than the 10ca, as it is titled "73" built in "72".
