...as referenced in the '72 S driver's manual: "When replacing a worn belt make sure that the replacement bears the designation Phoenix-Rhombus DA 9.5 x 710." So it must be correct for my toolkit (but no doubt someone will chip in and say 'no it's not'...).

NOS preferred please.

Please PM me if you have one.

Found one via ESR, not '71-dated unfortunately (May '73) but apparently '71s are like hen's teeth. This will do for now.
