I wasn't on the planet yet , when they made alot of these , so I don't know for sure , Keith .
I would really guess that the hardware , unless it was made of wood , would NOT be painted .
You can , of course , test your hardware with a magnet to see if it's steel ... if so , proceed with gentle caution , in the event it's original hardware & chrome or nickle plated .
Even brass was sometimes plated too , so go easy on the paint-removal if you decide you're going to chemically strip your cabinet & hardware ( don't use heavy-duty abrasives/abraders ) .
It's all messy & stinky work , refinishing ..... if you do it right , the finish should last a lifetime ( depending on how 'hard' you use your cabinet .
If you're going to use white paint on it , I'd suggest a high quality Marine Spar varnish .
