I'm no map history expert (though I play one sometimes!), but I live in
Northern CT and am familiar with the maps that you are talking about.
Mass. seems to be the only state that I have seen these maps. There are
additional 1:25,000 maps - not just those three. I'm not sure how much
of Massachusetts was done at 1:25,000, but a lot of Western Mass. was.
I think they were produced by the Commonwealth and the USGS used the
base mapping for its series. To be honest, I've never seen 1:24000 maps
of these quads, though I do believe that they exist.
I hope that helps.
