I would advise AGAINST pressure testing an 80+ yr old radiator, UNLESS it's at about 3-5 lbs. JMO FWIW

On a side note:

I once had a racing motorcycle that developed some liquid on the rim of the front wheel. I couldn't see where it came from, but in that area it could be brake fluid, fork oil, or coolant. I touch it, I sniff it, I ponder, I taste it. Oh, now I know. That's cat pee!

You are right Paul, of course. That is what I stipulate when I take an A radiator to my shop. I should have made that clear.
