I don't know if those 2 companies were separate, or if the first one became the second one. Since they have some of the same officers, I suspect it's the former.
Also, I don't know if they're related to the Bristol Drug Corporation, which is what the artifacts below say on them. The first newspaper mention I found that said "Bristol Drug Corporation" was in 1936³, and the last one was in 1951⁴.
