Tom is definitely the historian amongst us, but I know enough to blow my toes off one at a time if I aim well.
I did find an interesting picture recently that I was told hasn't been published, but I was also told that the two or three gentlemen on the far right are the principles, one supposedly Morgan. Tom, do they look familiar to you? I don't know them "on sight". I was told this shot was taken about 1901 in Norwood (suburb of Cincinnati) before the "clock tower" was added to the front of the USPCC factory. Looks right for the period clothing-wise and everything. The photo was obviously taken with an old lenticular I think is the right word - camera. Notice the bowing in on the right edge of the picture...
