Any modern oil is better than what they had then. My tags say 10w if below 32 and 20w if above. I use 30w castrol or briggs and stratton 30w. They all work as long as your level is right.

I use nothing but heavy duty #30 detergent oil in all my 4 cycle air cooled engines for summer use. Currently that's Co-op brand DMO - (Diesel Motor Oil). Been using the same stuff in the employer's John Deere 4240 tractor for last 20 years or so. It's on the verge of turning over 13,000 hours and engine has never been opened up and never add oil between changes.

When temperatures dip below freezing would suggest switching to 10W30 or if really cold, below zero F, you might want to go with 0W30 or 0W40 synthetic.

Now if the engine has been run on non detergent oil, you will probably want to stay with that, but I would still use #30 rather than a multigrade for summer temperatures.

Bill

50 year old engine. You might want to consider removing the base of the engine to remove any sludge that's accumulated over the years. If there's sludge and you use a detergent oil you'll run the risk of damaging the engine.

Briggs recomends 5w-30 for winter oil in their engines. 30w for the summer.
