Hello Mylo. Welcome to AOS.
Vintage Tannoys are popular here. Why not start a thread in our Past Masters section and ask any questions you may have.
There are five versions of the Chatsworth model all use 12 inch drivers. The earliest had the Monitor red unit, then the Monitor Gold driver with pleated cone surround, then Monitor Gold with rubber roll surround, next Monitor Gold with foam roll surround and finally Monitor HPD, also with foam surround. The cone surrounds on the first three don't perish and are likely to be OK. If those you are interested in have perished surrounds, best not use them, as the coils may rub and get damaged. They are comparatively easy to fit new foams to.
Enjoy the forum,
Geoff.
