Since the Concept is a little unusual in shape I don't quite trust that it can be considered part of the generic 'Selmer' which the Rovner Platinum fits--can anyone say for sure? Thanks!
Contact Rovner. Send them a mail or call them. They are very helpful. Or they were when I called them a couple of years ago. Very nice girls "on the office".
I sent them a note on Friday and they answered 'yes' yesterday but asked for measurements just to be sure. I sent those yesterday, so far no word. Eh, I'm getting used to putting a piece of card under my Selmer single screw. 🙂
