Good questions
All Taylors have bolt necks. In 2000 they went to the NT, with a non glued bridge extension.
But the earlier ones are bolt on too. A bit more work to reset, but still much less than a completely glued in neck!
According to my pal Tim Luranc, Taylor's employee #1, and the head Luthier for R. Taylor, the switch from nitro to UV poly was in 95. So 94 was the last year for nitro.
Enjoy that golden oldie!
