Could be someone already replaced them with even wire gages only? I have an old stringing guide which indicates the following for treble music wire sizes: M-SA - or M-2, with vertical Acu-just hitch pins 13 3 13.5 4 14 4 14.5 4 15 8 15.5 6 16 6 16.5 8 17 6 18 4 19 2 20 2 These a slightly different configuration of M-SA without the Acu-just hitch pins so, if that's the one you're working with, let me know and I can send those.
