Another period correct tyre to consider is the Michelin World Tour, I’ve put a set on my Claud Butler restoration.
I've still got two part worn 38mm World Tours in my take-offs pile to use up that date from 1988, and were fitted to my Raleigh Gemini hybrid when it was made! They look a bit scruffy, but they're still sound.
They're quite a stout tyre, but not puncture-protected as such, unlike the HS159.
@biggs682 uses HS159 as his replacement tyre for any 27" wheels he wants a tanwall on. I believe you can still get Marathons in 27", which have better puncture resistance than HS159, but don't look quite so correct on a drop bar bike. Not so out of place on a roadster though, because generally 3-speeds tended to have black tyres rather than tanwalls anyway.
