I would say you have a bad wiper contact to the resistance wire. Perhaps along what was shown of the gunked up wiper Larry Reber posted in his photo.
Have no idea what the range should be or even the brand gauge your 37 used but doubt the max number will be much over 100 ohms until you get into postwar cars. Stewart-Warner magnetic gauges which Packard used with 41-47 Clippers used the old 100 to 0 S-W range and even the modern S-W range only goes to 240.
For what it's worth here are a few typical ranges. Except for the 48-50 Packard models the other years should all be straight resistance senders. If anyone knows the ranges for another year Packard I will be glad to add it to the chart.
EDIT: Updated chart with 37 sender resistance as was found by Kev.
