This a HONDURAS MAHOGANY (Swietenia macrophyla) back and side set for building an acoustic guitar. 

Also known as Gunuine or tropical mahogany is an excellent tonewood with very wonderful tonal qualities, imparting a well rounded, crisp, warm tone.

 Very nice ringing taptone.  Works and bends very nicely. 

The measurements are as follows: back boards (each half)  8.5" x 21.5" x .130+" thick. The sides-  5" x 32.5" x .130+"

All of my guitar sets are properly dried and seasoned and ready for sanding.   Bid with Confidence!
