Figured this forum might be better equipped to answer the question.
I've got a 92 Paramount with Shimano 105 36 hole hubs/anodized rims)
I'm looking to build up a lighter wheelset for those 'quick 30 milers' the club does on weekday mornings.
I'm wondering if anyone made (still makes) a 28 hole 7speed rear hubset.

7 speed isn't in vogue any more so you'll need to search far and wide to find an older 28 hole hub with a 7 speed sized freehub. I'm also guessing that your Paramount may have the older 126 mm dropout spacing as well?
An option if the search for the actual hub fails would be to find any 7 speed hub in good condition and don't worry about the hole count. Then find a more modern 28 hole hub or even the whole wheelset but with Shimano hubs. Then swap out the freehub and axle assemblies to make your own 28 hole hub or adapted wheelset.
It may also be possible to buy a new 7 speed freehub to fit to a hub or wheel but that will still leave you to play around with altering the axle and cutting it down to properley fit your frame spacing.
I came here this morn seeking similar assistance. I have a 7 speed free hub wheel (shimano 105) that must be replaced as it will just longer stay true. This sounds like a lot of work to keep this bike in use. This is the oldest of my 3 bikes and the least riden, but still fun.
Other similar issue is 8 speed campy record rear wheel. I'd love some aero rims with fewer spokes.

It's never a lot of work if you enjoy tinkering. Think of it as quality bonding time for you and your bike.... :D
If the wheel won't stay true that sounds more like a spoke and rim sort of issue. Either your spokes are wildly out of whack for tension or if this is a really old bike your rim may be starting to wander from the brake track having been worn so much. Are the brake tracks heavily cupped?
