i love the vintage stuff,my williams tonsorial is at least 1960s i think.my analogy-old williams is like buying a new car-works as it should and a pleasure to use,but the shock absorbers wear out slowly enough that one doesn't notice.then 60,000 miles later it bounces around over the slightest bumps feeling undrivable.the newly installed shock absorbers aren't as good as the original ones and car doesn't ever feel the same..now i haven't used williams that much but for a 10 year stretch 2006-16 exclusively,the difference between my vintage and my modern was night and day.i did get some great lathers from modern but it took a bit of finesse....
