Most likely the original seal has deteriorated in the last 70 years and the box will not hold oil. A modern replacement seal for the bore and shaft size will do the trick; then use a suitable gear lube of your choosing.
Chassis grease and similar products will not leak, but they will form a pocket where little to no lubricant will be. It is unlikely that it will get hot enough to melt the grease to "flow" back against the gears.
Good luck,
