1972 Yamaha FG-75 - 21024554 T0214154

Hello I have an FG-75 tan label Made in Taiwan "no taiwan" labeled guitar. I have been hearing that these are rare because Yamaha only used these labels for a few months. The guitar needs new frets and definitely a neck reset and probably saddle and bridge repair as well. I traded a Recording King Dirty Thirties guitar for this Fg 75 and I feel like Im sitting on a rare but unusable guitar. I just want a guitar that I can play and feels good to play, but i like this historic guitar. I can hear its undelivered/ broken potential. This thing doesn't feel good to play but I still appreciate it for what it is. Anyway the serial numbers are:

20907112
T0195875

From what i have gathered this guitar was built september 7th 1972. What does the "112" part of the lable represent? Production number? Any information that you have on this specific model would be appreciated if you have the time.
