Scale Length?

[Out of Limits]

I've searched the forum, but haven't found a definitive answer on this. Can anyone confirm these two measurements on a MkI?

1. Zero fret to 12th fret.

2. Zero fret to 22nd fret

The first will give the theoretical scale length and the second will confirm which method was used to calculate the fret spacing. I know I could use a nominal 24.75" scale fretboard and place the bridge accordingly, but I'd still like to know how Semie Moseley did it.

On mine, from the center of the zero fret to the center of the twelfth fret is 12 9/32". And from the center of the zero fret to the center of the 22nd fret is 17 23/32"

Perfect, thanks. Those measurements match my GIbson rule of 18 template, so I'm all set.
