Sara,
I believe the pump books prices this pump at around $1300 complete in very good shape with a good original cylinder which is probably a light blue tinted one.
As for a globe, it does not matter what company or brand it was you could do any one that is in the time frame for that pump. Most likely it had a one piece etched or baked on globe or a metal body globe but could also have had an early three piece glass body globe. Some early major companies were Texaco, Mobil, Sinclair, Shell ect. Just use a globe that is from that time frame of the 20's & 30's. If you are going to display it outside with a globe on please use a repro globe.
