I have never owned a National pump, but the Gas Pump Bible does not show any National pumps without the rounded ad glass and a higher top than you have pictured. The Bible does show pics of the National 360 and 365 which look like your pump, but the description says those were Tolkheim 300 pumps with National name and both have hose retractors. It looks to me that the top on your pump is a top from a Tokheim 300. My cell number is in my profile if you want to send me yours, I can send the Bible pics I mentioned unless you want to scroll the internet and see what you can find.
