Help: Schaller M6-IND locking for Silhouette Special

My Silhouette Special guitar’s peg (for 1 st string) is broken and I can’t release the lock…
According to the current spec on the musicman guitar page, the peg is Schaller M6-IND locking but I can’t find the peg in Schaller site.

Does anyone know what peg in Schaller is same as M6-IND which is used for Silhouette Special ?

I would like to order the proper peg in a local shop.

Thanks for your help!
