It is rather unusual to see a Dura Ace freewheel hub spaced that far out though.
and that far off center too...
it appears to be a homespun "i'll change this to 135mm!" hack job.

the 132mm width dropouts were intended to fit either a 130 or 135mm O.L.D. hub... and didn't work well with either option.

i had a project road bike a few years ago that came to me with a 132-ish dropout width... i reset it to 130.

*that must be the ultra-rare Campy Super DA group's hub...
