I had some Ilfobrom from the 60's also Kodak Bromide papers and both were fine no base fog and not much drop in contrast maybe half a grade. I gave away about 500 sheets ironically on the Ilford car park at Mobberly.
It's warmtone papers that age the quickest but I've my fingers crossed for the Barnet paper I acquired recently.
I've also some plates for my Quarter plate cameras, I cut my teeth on HP3 .
You never know until you try these older items but might be surprised.
