Classic/Antique Car Repair: 49 Ford gas gauge, hemmings motor news, gas gauge

Question
I'm looking at a '49 Ford Fordor to purchase - the car is 95% original. One of the minor problems with the car is with the gas gauge. It registers between half and three-quarters full until you're pretty well out of gas, when it drops down to read empty. The current owner has boiled the tank, replaced the sending unit, and the wire from stem to stern so it makes sense it could only be the gauge. My question is, are these 6-volt gauges fairly easy to recondition? What would be my best bet to get that problem fixed without going to an aftermarket gauge?

Thanks in advance.

Answer
These gauges are easy to find, and there are those that will rebuild them. It sounds like the dash unit could be the problem. My standard answer to any question that starts with "where can I find.." or "I am trying to find..." is to get hooked up with Hemmings Motor news.
