Two attributed to Dave Tesch look like they were out of the 101 series design, "Built for Speed".... I wonder if anyone was aware.
It is also possible that these geometry variations are based on building inconsistencies. Some time ago there was a private email group that owned Italian Masis and there were variations between frames that were obviously not planned. Also there can be measuring variations based on whatever method was used. As a framebuilder I would be interested in the methods used to make the frames. This information can be well hidden.
