Matt,
What I work off of is original factory literature, I don't have your experience in dealing with each exact pump. I will say this, I don't believe any pump company ever made a nozzle. My literature indicates, this was one of the many items they used that were made by some independence company, such as in the case of what you are showing above. Bennett was so large and ordered so many nozzles they could request their name be put on every nozzle. The same with Tokheim as it appears that OPW made every nozzle they used, or at least most of what they used. Pump companies were in the business of selling pumps, not nozzles. I will admit, I have never seen a nozzle with the name Bennett engraved on the nozzle, nice find. My factory literature doesn't state who made the nozzles, so all I can do is to compare a particular nozzle with a picture in an OPW, Morrison, etc. catalog to determine who made the nozzles.
I will all this, I was in the Bennett factory the day they closed the company, this was not a large factory. I actually believe they had a great deal of parts made either by independent companies, or off site factories that Bennett owned.
