It also fits your description of thin dark bands in light background. The sound is deep and resonant. It's a beautiful guitar. Now I need to learn more about the maker--have nothing other than one owner said Mercado was apprentice to Manuel Velazquez. I have not found anything on the luthier to confirm. Thank you for your help!
You are welcome! It's lucky that others confirm my opinion, too. Here is the textbook definition: Indian rosewood (EIR) has fairly regular, uniform, wide stripes, with an overall dark appearance. BRW has thin and thick stripes, rather irregularly distributed, with an overall lighter appearance. BRW often has wild grain formations, runouts, sudden curves, etc.
It is a really beautiful guitar! Congratulations!
