I think B&S, Weltklang ... made saxes for other brands that was actually out of production. I've owned and played French , Dutch, West-German and American saxes that I got a feeling that they was made behind the iron curtain. Some firms said that thier saxes was made in Eastern-Europe, like Boosey and Hawkes, Corton and Lemaire. I guess a silverplated B&S was actually made for another company/brand. Maybe they got a couple over that they could sell under thier own name? Most DDR saxes was made as student saxes.
Sweden and Austria had "good" connections with DDR and Czechoslovakia because the were both neutral contries. In Steyr, Austria UMI had a European office. The Musica Steyr "factory" didn't have any real production. All this changed after 1990. We have lots of DDR saxes here in Sweden. Many good musicians started to play on saxes with bad ergonomics, un-balanced, bad intonation ..... . How was it possible?? I'm really looking forward to the next generation saxplayers. They don't have to struggle with bad saxes!!
Nowadays I think all saxophone manufactoring is closed down in former DDR. Amati-Denak is still in business. But it must be hard for them to compete with Chinese and Tawainese saxes?
East-Germany (B&S, Weltklang.....) had a long tradition of making saxes and I think they were good ( I could buy three Weltklang low A bari for the same price as one Selmer MkVII bari. And the Weltklng was better on a small clubscene. I played bari in a punkband in the 70's!) The knew how to built saxes. They didn't copy other saxes. They did thier own products.
Take care of your B&S. It can be a milestone reminding us of the era when "East was East and West was ..." . But I think it was pretty much mixed-up!! I like the dark tone. A good ballad sax. A slow blues is also coming out fine on B&S.
