Ive just seen an old type pace (card) box working happily away. I asked the lad what he had done to get it back on again, and he said "nothing, just got it out of the loft and tried it!!" Ive got one buried behind a mound of xmas prezzies, so might give it a try when I can get at it...on boxing day!
I believe that most non-carded boxes (if not all) have gone down, but some carded boxes may still work
