I've owned this 1969 Martin guitar for 47 years of its 57-year life.  1969 was the last year that Martin used Brazilian rosewood as standard for their rosewood guitars.  It has Martin's standard 1-11/16" nut width with 14 frets to the body.  The Brazilian rosewood is beautiful and the sound is great as you would expect.  The action is low and easy to play at 3/32" under the bass 'E' at the 12th fret.  The neck relief is small at about .010".  The scale is standard 25.4".

The guitar is in unusually good condition for a guitar this old, and you will not easily find another one as good.  The guitar is structurally sound and clean inside (see interior pictures) with no top or back or side cracks. It does have some minor wear on the bottom of the sound hole and some natural wear on the back of the neck in the first position as pictured.  It has some minor scratches, dents and dings on the neck and body. Zooming in on the pictures will help you to see some of these.  I don't see any lacquer finish checking, which is unusual for a guitar this old, and the finish is all original and amber colored from age. Likely it avoided finish checking since it spent most of its life in a mild climate without big temperature swings, and it has lived in a non-smoker home.  The neck has never been reset and a reset is not needed.  The original Grover tuners work fine.  The fretboard is very smooth from beginning to end with no divits or pits. (Players with long fingernails cause deep pits in fretboards.)

The guitar is all original except the following:  The nut was replaced and a compensated saddle was added (The original nut and saddled are included in the case and could be reinstalled.).  The original pickguard was replaced since it was lifting.  One small 1/2" spruce cleat is glued inside the top under the pickguard.  Due to normal wear, the first 6 frets were replaced with identical fret wire so that the frets now have very little wear.  The bridge's ebony wood between the bridge pins cracked and was reglued.The end pin was replaced and a simple strap button was added on the heel as pictured. When shopping for a vintage guitar, make sure you get the seller to give you a COMPLETE list of past repair work and whatever is not original, especially the finish. Most sellers seem to avoid a thorough description of the condition and avoid interior pictures of vintage guitars. As a collector for many years, I suggest that you make sure that you get these BEFORE you buy.

The case is original and is in good condition. All hinges and latches work fine.

Please let me know  if you have any questions. 

Thank you, but I'm not interested in trades. I have been selling off a significant part of my right-handed guitar collection this year and have shipped several expensive guitars already (1948 Gibson LG-2, 1952 Gibson J-45, 1956 Gibson J-50, 1968 Martin D-12-35 Brazilian) after listing on other sources, forums (Sugarlander) and stores. I recently sold a guitar on Reverb for the first time and I may list more, so be on the lookout.
