What Changed in 1975
Martin's quality was consistent through the 1970s. The D-28 remained the gold standard reference acoustic, now with Indian rosewood. Factory output was high — these are widely available vintage instruments.
Collector's Notes
Martin quality in the 1970s is often underestimated. These are professional-quality instruments. Check neck reset (often needed) and look for replaced saddle/nut. High production means plentiful supply keeps prices accessible.
How to Authenticate a 1975 C.F. Martin & Co. D-28
Martin serial numbers are the most reliable in the industry — verify the number stamped on the neck block (visible through the soundhole) against Martin's published tables. For 1975, the number should fall within the documented range. Indian rosewood back and sides — verify correct grain and coloring. Non-scalloped X-bracing pattern for this era — verify through the soundhole. Check bridge for original belly-style construction. Martin stamps the model number inside — verify with a mirror. Check for neck resets, top cracks (especially near soundhole and bridge), and bridge plate condition. Tuners should be Grover Sta-Tite. Finish should be nitrocellulose lacquer with age-appropriate wear. Original case adds value.
