B flat clarinet made by J.B.Albert REALLY old

My Mom gave me this clarinet. It was given to her by a man who used it in the "Halle Orchestra" I don't know exactly how old it is, but it seems very old. I can't find very much info on the maker, but i know its English. The markings on it read "J.B. Albert Bruxelles". "J.B.A. / AINE". toward the bottom it also says "Brevette"
The mouth piece is a little different. It reads "G. Howarth & Sons 73 York Street Bryonston S03" ???
