I beat you, I am 82 and I have what I believe the largest collection of service station literature. This literature includes not only gas pump companies, but any company that made service station equipment. My literature goes back as far as 1886 and includes catalogs that sold hardware but also a gas pump.
Just go to this list of catalogs that I have: http://petrolianacollectibles.com/catalogs.htm
This list was created in 2014, I have many more.
I should also include, I have 41 file drawers filled with gas pump literature, you name it, I have it.
Actually I am not trying to sell what I have in a bulk. As soon as my next gas pump book is published, I will be putting my entire collection up for sale. At 82, I would rather take a trip to Ireland than look at it.
