Coool! I saw a set like this listed on eBay recently - in fact, I think we commented on them at the time?

The '58' stamp could be an indication to age - it certainly has that 'look & feel', IMHO. It alludes to being 'Decorated in England', which suggest the glass could be foreign, so that might be worth following up.
Great forum this - if it isn't Chance, Pirelli or Ravenhead...
