Years ago when I did television service I had a meter with a high voltage probe with which I probably could have measured that voltage. No more!
I would be surprised if you have the equipment to measure it. There are coil testers which perhaps your auto parts store may have. Would not even count on that. Not sure how reliable they are as coils typically fail when hot.
You can measure resistance but I don't recommend that either. The voltage in your multimeter may be high enough to produce a nice, shocking spark.
Best test for most of us is to determine if it works or if replacing cures the problem.
I cannot tell you what the high voltage value should be. Much lower on these N's than you will find on modern vehicles with electronic ignition.
I do have a 1958 Ford shop manual which may yield further information when I look at it later today.
