Feels like it, but, no. I checked it against the '71 D-25. Precisely the same width.
The neck profile is a little thicker, though. It makes it nicely playable.
That’s great!
I remember when you were parting with the F-50r and you said you loved the guitar, but you were struggling with, or just didn’t care for, the long scale and narrow nut width.
A chunkier neck profile can make the skinnier neck feel better! So will you use lighter strings, or lighter tension strings, to make it feel more like a shorter scale? ( at least tension-wise). I put 11s on my Maple F50 and JF30 because the Significant Other likes those two guitars best and she finds the 12s too stiff. I like them, but for my needs I prefer the 12s.
Glad you found a keeper!!
