You are all wrong. First this pump is basically the Tokheim 300 with a different top, and the stainless trim & the ID tag says National. Tokheim acquired National, they stopped making the National pumps where the letter in the ID tag was first, then the number (example A-38). Tokheim changed the model numbers to be number first, then the letter. Take a good look at the ID tag above, this pump is a 64-B. The 64 had the 17' hose, where the 62 had a 12" and the 66 had a 14.'
Picturers of all three pumps are shown on this page

But, Amazon does sell a e-book copy of my book for less that $15.00. They quit sending me royalities a couple of years ago, so I don't make any money anymore.
I believe what you have is a porcelain pump, be carefilly with it, they chip easy. Use a good paint remover and polish the porcelain
