Up for your consideration is a used Washburn D60 SW Timber Ridge 1978 MIJ with case. These guitars rivaled Martin, Taylor, and Gibson for their sound and quality and construction. I believe this one was built by Terada Gakki, the same company that built the Shenandoah series for Martin. However, we don't know exactly who built them, the records are not clear. 

An all-solid wood made in Japan acoustic from 1978 thru 1983, during Japan golden years of guitar building. Early versions were built by Yamaki. It is almost identical to the Yamaki Y60D, which is solid mahogany instead of Ovangkol. The only other differences are the fret board markers the trim on the head and the shape of the head stock. There is a minimal amount of man-made material, binding is multi layered maple and rosewood. The soft V-shaped neck is very easy to play and comfortable. The action is set where it should be about 2.25 mm at the 12th fret on the 6th string. It has a bone nut, saddle, and bridge pins. Comes with a hard shell case that fits perfectly.

If it were not for the following minor flaws, I would list this guitar as being in excellent condition. There is a hairline cracks above the fret boar on the base side, which has been repaired (see photo). There are a few other bumps that are consistent with a guitar of this age. 

Comes with a hard shell case.

These are excellent guitars that rival Martin's for sound and quality of workmanship. Do some internet research and find out. The only reason I am selling is that I have two of them.

This is a used item and has minor defects such as scratches and dings in the finish. I do my best to show all major defects in the photos and description, but it is impossible to account for every small defect that can be expected on used/vintage items. I only state this obvious fact because I learned the hard way that if a buyer complains that they could not see a small scratch in the finish and I do not mention it, E-bay may view it as a legitimate reason for a buyer to request a refund. Please ask questions if you have concerns. I never describe anything as new or mint because there is always some small detail that can be missed, items are "sold as is." I will be happy to take additional photos if you need me to. Thanks for your time and understanding.
