I've always meant to measure VIs going through my hands and compare to my VIIs. But I never had the time.
But for your speculators out there thinking there's no differences between VIs and VIIs (other than the keywork) here a nice pic of the Bow which clearly show the tonehole size differences. I was shown these years ago at a Ferrees dent class.
I personally think they are mis-marked as my VII has much larger toneholes than the one marked in the pic and they are more placed with the one with the larger toneholes - but maybe they changed them .. M versus N tubes ??
