I have a Schenkelaars alto made by Arta Guban. Hanging on the wall. Interesting saxes.
Yes, I have a professional relationship with Uwe. He has given me written permission to translate his original material for my website. In turn I provide the credits in exactly the language he has requested. See example at the bottom of the D&J page.
So now that we have my situation cleared up, to answer your question, well... By law you may well be violating copyrights. However, if you send Uwe an email and ask him if it's OK that you do this. he will let you know one way or the other.
He is a very nice guy, and can read and write in English. (Although writing in English is not as easy for him as German is.) He is very approachable. You can find him through his shop.
BTW Jaye, not to derail your thread, but I did find a low A bari. I got it through Paul Maslin. It is a very lovely H. Couf Suberba II in black nickel with gold plated keys. It was a closet horn. Although I'm sorry I couldn't get a bari through you, I'm not at all sorry I got this stunning beauty that has a sound that will knock you on your as!.
