I am presently working on a gas pump identification book due on the publishers desk, Nov. 1. There is also under consideration a book covering all the other equipment used in a service station including nozzles. Since I have information and pictures on over 1500 gas pumps, I can look at the pictures or the parts manuals and see what nozzle was supplies with the pump. Some companies had nozzles made for them (I don't believe any company actually made their any in the own factories) but most of the companies supplied their pumps with OPW or McDonald nozzles. Many pumps are being displayed wrongly with nozzles with the clip to hold it open, as this feature did not appear until the mid 1950s. One more thing, most pumps came with a choice of two nozzles to be included with the pump, one with a flex end and one with a straight end. Email me a list of the pumps you want information on and I will try to get to it. This book deadline may delay me for awhile.
