Thanks for that Colin - I don't know why it (or I) created a duplicate - no way the poster can remove it, unfortunately!
Yes, I think I may have to order from overseas. Kool Classics offered to make me a table, which may mean they can source the profiles, however they are very slow to reply (as always, though they have sourced a number of strange parts for me over the last three years!). The table I have bought is a freestanding one (for now), which at least gives us a table for now...
