Interesting variation on a D-44. All the ones I've run across have been pale pearwood and not stained, as D-40s were during that period. (My '65 D-40 is a deep, almost cherry red.) There were also pearwood Mark classics.
The guitar in the Norm's video also has a reddish-brown color that must be stained, as well as the same design tuners as my '65--basically open-backs under a teardrop-shape dust cover. I've not seen those on many of the older Guilds I've encountered. Another odd (to me) feature is the volute, which my guitar lacks. And the saddle has been replaced or altered--it doesn't go all the way to the end of the through slot on the bass side.
In any case, mid-60s Guilds are very good guitars--better, to my ears, than their 70s descendants, which became a bit overbuilt.
Addendum--after Googling around for photos, I see that most of the 60s D-44 examples are stained, some of them in that familiar near-cherry shade, and that quite a few have volutes. More evidence of variability from the Guild factories.
