Jerry,
>From my experience, the 172.5's are typical. I've seen about 8 or 10 early
Pro's and all had 172.5's. My experience has been that around 1972/73ish
they went to 170.0 as the standard. Maybe of interest too is that the early
Team Pro's from Ilkeston specialty shop seem to have come with undated
172.5's - at least on the 5 that I've seen in person including my own 1974
SB19.
