I've been scrubbing the interweb for relevant information on the discontinued Walnut-Series Taylors (i.e., the W-** guitars) --
not the 2011 Spring Limiteds that were also done in Walnut, and confined (I believe) to 6-string models (W12, W14, and W16). I'm interested in sampling a 12-string Taylor in Walnut, so I'm curious what's even out there...?
As near as I can tell the W-Series was still regular production up until the early- or mid-2000's...? I can't seem to pin down exactly what years the series ran -- or for that matter, exactly what models were part of the series. Again, I can pull down some spotty information off the interweb, but it's incomplete at best -- and least of all, Taylor's web site is of no help; it's woefully inadequate when it comes to historical information on their products...

Anyway, based on what I've inferred, there appears to have been a Grand Auditorium 12-string (W54), and Jumbo 12-strings (W55 & W65); not sure whether there were any Grand Symphony 12-strings (i.e., W56 & W66) in the series, as it may have been discontinued before the introduction of the GS body in 2006.
Any insight and wisdom is appreciated!
