Thank you all for this input.
I’m hesitant to go looking for the queen for fear of undue intrusion/disruption.
Only 3 of the frames had comb. Each comb was half the size of the palm of my hand.
3 or 4 of the other more central frames had clusters of bees the same size as the combs. These clusters dropped to the floor of the box when I lifted those frames. I assume this grossly interrupted their effort to build comb.
Even if I decided to disrupt the clusters enough to find the queen, it didn’t seem to be physically possible the way it would be on well formed comb when the bees are only 1 bee deep.
I’ve not yet found any clubs/associations that meet regularly enough to have had a meeting in the last month. I’ve not yet developed any relationships with keepers to to ask for brood comb, but thanks for that idea.
*** I don’t want to go off half cocked, but I’m wondering now how to gauge the moment when/if to order a new queen before I lose the workers or end up with a weak population that won’t survive the winter,
