Difficult to say. Homer made mistakes and you know the registry if far from complete. Those are "special" tuners, maybe you can find a matching description in the time line?

Somehow I ended up with quite a collection of Ledfords. Most are identifiable from the master list (which, naturally is not complete). I have several early ones including two before he started numbering. Recently, however I acquired one which did not have a number assigned. [There is one on the list unnumbered.]

It has staple frets (long 3rd), early style hearts, and an unusual construction for the fine tuners. It was made of yellow poplar (very dark brown) from 150-y.o. church pews, which locates it from 1969 to, perhaps, 1979. The label also has "Winchester, Kentucky" spelled out.

I'm trying to zero in on an approximate date; does anyone else have one with a dark poplar top and/or a "Kentucky" label and/or the tail plate with fine tuners.
