The FM string is there, but the am/sw dial string is long gone

The above dialcord diagram is from a set that is several years older than yours; but the arrangement is very similar. SABA got a lot of use out of this design!
Changing the FM cords is relatively easy (but fussy) whereas the AM cords are a bear. There should be a removeable plate in the dial that will facilitate things a little (but not much). Useful tools for this job are medium-sized crochet hooks, masking tape, and a couple of surgical needle holders (forceps).
Not sure how to counsel you about the AM drive cord (the inner one) if it is intact. If it were me, and I had to replace the AM dial-needle transport cord (outer one), I'd go ahead and replace the inner one, too. But it is quite tedious to do so. I've done it, so I know that it is possible, but just barely (although maybe my memory is inflating its level of difficulty). I believe the AM drive cord was installed at the factory as part of the tuning subchassis, so it was a relative breeze at that level of assembly. Once put together, it becomes very challenging.
Hello Adam, Here is some more service information from Private SABA forum Page 14 has dial string info For the Freiburg 15m. Maybe it will help. I'm not sure if Frudenstadt 15m is the same.
