Thanks for posting this tale.

I have a different story about the 1928 Martin 0-18 that was my Grandfathers.
Grandma bought it new for him, and gave it to me in 1965 after he died.

Mine is in very good condition, largely because
1) he didn't play it much, was careful with his things, and
2) I have always treated it like the treasure it is.

I hope the grandson of your lady friend is tuned in.

Be aware that a 1924 00-18 is probably not be braced for steel strings.
That's about the transition time.
(EDIT: see post below by Osage)

I keep mine .. which IS braced for steel.. tuned down a full step with low tension Silk and Steel strings.

Again, thanks for sharing.
