Looks like a 906. To confirm look closely at the trim ring around the reset crank on the side opposite the nozzle (see attached photo). My first was a Gilbarco 906 as well. By far the easiest of the four that I've restored.

You can order a parts guide and most of the parts you will need from Vics66.com. I'm not sure if he would have a metal top cover though

I restored mine as a Sinclair pump. Still my wife's favorite.

Let me know if you have any questions.
