Picture doesn't show a bonnet.
It's almost 2 in the morning, don't want to do a lot of research, but it looks like any pump in the 600 Series (600-605-610-620-620B-625-660 or 665.
First, you keed to purchase a copy of my Gas Pump Identifiction book, while you got a great deal at $100.00, you should be glad the seller didn't have a copy of my book.
Go to this section of my website: http://petrolianacollectibles.com/tokheim%20pumps.htm
Look up all the model numbers I have listed above, if this dosen't help you to identify the pump, you might need to post some better pictures.
