If you don't own a Brazilian rosewood guitar, you may not be interested in a Brazilian rosewood tiple (such as are at Elderly). Here are a couple of tiples in stock at Mandolin Brothers. 83-1681 C F Martin 1975 T-18 Tiple, 370411, near mint, OH. A late model tiple in wonderfully clean condition, the T-18 has high quality mahogany back and sides, wide grained Sitka spruce top, multiply bound in black but with a tiny tortoise type guard (not made from Timothy Turtle). Head plate overlay is Indian rosewood, and it is blessed with three entire fretboard dot inlays of declining size. The tuners (5-on-a-plank strip) are nickel plated with white buttons. The condition is utterly stunning, looking almost as if it was born yesterday. On this instrument you can play your favorite rag: The St. Louis Tiple. **$1134
83-1122 C F Martin 1955 T-15 Tiple, 145580, vg+, OC. The all mahogany body 10 string Argentinean folk instrument, strung in four courses of 2-3-3-2 and tuned to A D F# B. This is a clean old thing. **$644
This might serve as a aid to you in gauging the price of the one you're looking at.
All the best, Dan
