Small gas tank question

Here are two of the smaller sized mercury single line tanks. I’m guessing the one on the right with the smaller opening is older? I believe it is from a 110. Would the merc 60 have come with a tank like one of these? Any idea why they changed the size (or what year) of the gas cap at some point?

It may be more of an issue in the evolution of the tanks.

The tanks for my '68 Merc 40 and '63 Merc 9.8hp both came with a small filler hole.  So maybe things changed during the 1970's

The one with the smaller cap looks like the tank that was with my 68 model 60 (6hp) when I was a kid, by the time I inherited it had set with gas in it @ 30 yrs and
the tank and cap were rusted beyond the point of being usable, saved the fitting but that was it.
