First of all, its not a 49/50, its a 47/48. The smaller taillights, the 'ribbon' dash gauges instead of round dials, and the vertical/horizontal grill units confirm it. Is this car in the Registry? Does it have overdrive? If you look at and post the serial# and the info on the cowl plates we can sort out what it is and what it was. I don't have any idea of the value so I'll let someone else do that.
