ABB is what resulted from the merger of Swedish ASEA and Brown Bouveri & Cie of Switzerland.
There are specialist distributors worldwide who deal with the individual sections of products from both companies, we deal with ABB in Coventry UK for their switchgear.
There will be information around, it's just finding it, and it may not have been made by BBC (Brown Bouveri & Cie) in the first place, they may have bought it in.
