Apologies, but I've gotta go a little MythBusters
"When you hear hoofbeats, expect horses, not zebras."
Looks like you've already made up your mind that you know everything about your guitar, so I'm kinda wondering a little what it is you expect from us.
Yes, it's true enough that older modern Washburns (~1978-1995) exhibit inconsistencies in model designation... rarely
The "-S-" could mean just about anything, like "Special Edition." I own a D46CESP, which differs from the D46SCE by having a laminate
top in s
That said, I assume you guys have actually looked into the Archives, right...?
Therefore, the following is for those incapable of the work.
In the 1991 pricelist, the D-17 has not yet appeared. However, the DREAD. ACOUSTIC/ELECTRIC section notes that the D-29-CE has solid spruce top.
In 1992, the D-17-CE arrives, with solid spruce top, a feature shared by D-61-CE & D-68-CE -- not an "-S-" in the lot. (FWIW, MSRP $699.90.)
1993 finds both the renamed D-17-SCE (solid spruce top, mahogany back/sides, $789.90) & new D-17-CE ($829.90, all flamed sycamore, the word "solid" is NOT used).
That year's catalog of acousticals says
Solid spruce top on the D17SCE B and D17SCE N.
Bookmatched flamed sycamore top, back and sides on D17CE BR and D17CE WR.
This model was featured on the cover.
The 1994 list says the guitar has "bookmatched flamed sycamore top, back, and sides."
In 1995, the sprucetop disappears & the CE becomes "flamed maple top, back and sides" for $749.90.
The price is jacked up to $899.90
for 1996, a typical stupid marketing trick for Washburn -- in fact, it jumps another $100 for 1997.
Likely citing a sales slump
Washburn kills the model.
Again: note that it goes from flame sycamore (1994) to flame maple (1995). If the serial number is being interpreted correctly, the maple version wasn't available in 1992 -- therefore, a special run.
Now, at no point
do pricelists or catalogues EVER mention "Brazilian
rosewood," which would be really stupid because that's clearly a major selling point.
If you're dead certain it is Brazilian, then I feel justified guessing that the suffix "S" actually stands for "Special Edition" for some big retailer like MARS or Zzounds or Guitar Center. That also implies the "S" DOES NOT stand for "solid top" (whether or not ANY of the wood is actually non-laminate).
When you say stuff like i doubt very seriously that even washburn would put a Brazilian rosewood fretboard on a laminate guitar
, you make clear that you don't know much about Washburn.
If your father is living, you could simply ASK where he bought it from. If a major chain, then it's probably a special-run version.
If the whole guitar is actually made up of flamed maple... umm, all you have to do is look inside the guitar
The graining will be awfully goshdarn hard to miss, right? I'm kinda wondering why you've chosen to NOT show that in your photos.
If you still wish to claim the top is solid wood, then all you need to do is get a small mirror & photo the grain.
