Since you're posting this here I assume you're looking for the Zaccaria Scramble bezel ?
Because I've never ever seen a Stern Scramble over here in Europe....
You'll have the Zacc experts here what is the "real" Zaccaria Scramble bezel, there may be more than 1.
Luigi (Thorsten) has some nice NOS Zaccaria bezels for sale although I don't know which one's are still available....
