I haven't treated the inside... Is there any use in using frame saver on an old frame? I got the impression that it was something you would only do when new, but would like to be proved wrong there. The BB shell cleaned up very nicely after some WD40 and brass brushing with minimal rust, but obviously impossible to know about the rest of the frame.

It's a bit late, but it can't do any harm.

Even the BB doesnt look bad at all, certainly not at respray level IMO,so that would suggest to me has been quite well cared for before you. I agree with Lolo, might be worth just having a look inside the BB when its next out and running your finger inside the tubes. I also think a drain hole cant do any harm. Plenty with better knowledge than me on here though.
My 1979 Holdsworth (owned from new - srs paper round money that) had very little rust inside when I had it resprayed by Argos in 2014 and that had been left out in all weathers during its life.

Dont think there is anything much to worry about with the patina on the frame looking at the pics. You could treat the bb in isolation, but not sure it needs it? Think I would be more worried about the inside of the frame tubes, apologies if missed comment that had dealt with by squirting in frame saver or such like.
