I have a great deal of gas pump literature, most of it is posted on the page of my website.
http://petrolianacollectibles.com/gas%20pump%20literature.htm Incidentally, the site has over 12,000 service station pictures on it.
What you have found are oil dispensers. Look and see if there is a model number and if there is please post it here or send it to me at jhsim@petrocollect.com and I will see if I have any literature on it. My new Gas Pump ID book does not identify oil dispensers anymore, but I may still have literature on the dispenser.
