I've got an early '52 D-28 (one of the first 50 serial numbers) coming in five days. I can't access my books, I'm in the middle of renovations. I'm curious as to what kind of bracing, truss rod, and any other pertinent construction items it has. It's more of a player than a collector, but the closest Martin I have is a '57 D-28. Just curious, any info, or tidbits would be greatly appreciated.
Thanks in advance.
