There is something to be said for nostalgia, but I tend to agree with
@MattHooper that if you're in the market for bookshelves, there are numerous well-regarded options that are more technically proficient, or shall we say up-to-date.
That said, I had some B&Ws almost as old as I am (>30y) and they didn't sound half bad to me. If you are looking to go down memory lane with B&W my advice is to take a nice long walk. Over the past 20 years I think they've gotten progressively less neutral in favor of what you might call showy, splashy, or "showroom" sound.
Even though this model is a bit off-kilter I think most speakers they're putting out in present day are even MORE askew.
So if you want to recapture that magic, I think you should set up an alert on Craigslist, check FB Marketplace daily, check eBay and US Audio Mart regularly(or your country's equivalent), and Reverb.com and a pair should turn up eventually.
Or on a more practical and not terribly expensive front, I have some 602 S2s in my guest room and I think they're probably not far off, on-axis, from what
@JSmith posted. And they're not that hard to find secondhand.
