a "Ramble"
You would probably have to dig around in Rochester, PA. to try to uncover any documentation. Since we are talking pre depression era and most companies either went under or merged...it would be a tough search. Since Wayne bought out GLM(J.Sim, Gas Pumps, p.15), perhaps the information still exists in some archival collection somewhere.
From my own experience I have found that companies trash most of that stuff because it is just useless to them.They pitch it, especially when they move from one location to another or when they come under new management and they "clean house". We are also talking about a time when everything would have been on paper and simply a burden to accumulate and transport. Throw into this mixture elements such as an economic depression, a World War, advancing technology, etc. Why would one "save" this information...especially when everything old was seen as archaic and we had not yet begun to appreciate the aesthetics and beauty in the design and construction of many everyday objects such as buildings, automobiles, gas pumps, juke boxes, etc. It would be neat to uncover some old files which had all of the production figures and information though.
Perhaps the best source of information now is the collectors and restorers, "preservationists", such as the ones on this forum who selflessly contribute their time so that others may benefit from knowledge and/or experiences. Thanks guys!
