Back in the day, no dealer or broker could live without his Hambros, the little red book that contained a list of active banks, their key staff, telephone and telex (remember them) numbers and Reuters codes. When SocGen took over the venerable UK merchant bank, the book sadly went into decline. For the past few years, the now rechristened Reddbook has been published by 4Cast. While not yet quite restored to its former glories, the book is on the up and it is, once again, an extremely useful reference guide. ACI UK is giving them out free with membership, another reason to join the association.
