I've owned or borrowed a number of track bikes, ridden them on the road and on the track. I would say the majority of them have toeclip overlap - rega rdless of age. My circa-1938/9 Durkopp has significant overlap, at least an inch. Of course, I'm also sporting size 11 (46 in Euro) feet.
I also have a couple of road bikes with overlap, in case anyone want to exp and this discussion. I know that this is considered a "no-no" among thought ful frame builders these days, and these bikes were not built (too) recentl y - '70s and early '80s.
