I'm pretty sure that pressures were far lower in cars back then, so it might not have been too dangerous as long as you don't see steam coming out of the relief valve on the cap..anyone else want to chime in on this?
Worked on lots of 1950's cars... They had pressurized radiators but most did not have overflow tanks. Most of the time, people only wanted a radiator check if they suspected a problem. If that was the case, the water level was low and it would not spurt-out at you. Right, wrong or otherwise, we would often take a couple shop rags, cover the cap and slowly twist it off and let the pressure out. A lot of folks back then would just use water in the summer months and do a drain/fill with AF just before the winter months.
