It came with two different types of cranks, Stronglight on the driveside and Arregui on the left. The left one (Arregui) it leaves a gap of 5mm between the end of the spindle and the crank's outer side square hole ( I suppose the crank is ISO and the spindle JIS) The Stronglight fits deeper and leaves a gap of 3mm. The spindle is 118x55 GS. Do you know which standard Zeus complied with? JIS or ISO? Thanks a lot.

Arregui designed their cotterless chainsets a good two or three decades prior to the existence of ISO
have no experience of mixing Zeus with other brands so cannot comment there
no one in europe was designing to JIS standard back when Zeus tapered square chainsets were first created
other readers are sure to be able to give a better answer to your very reasonable question

sidenote on Verot-Perrin -
they performed a major reworking of their range in 1977
new models were introduced which employ a 22.0mm puller thread and which have their dentition cut from both sides of the stock rather than one as is found on older models
this new cutting of dentition means lands need to be thinner
mention this as there may have been other changes as well...
