|Martin 0-21 NY and 0-16 NY|
This same year two new Martins were introduced; The O-16NY and the 00-21. These guitars hold the distinction of being the first vintage re-issues of a guitar. By 1961 the popular Martins were series D guitars.
my 0-16NY to the factory twice I was told by a Martin representative, this guitar was very lightly braced and actually designed to use silk and steel strings. Remember, these guitars did not have a truss rod. The 0-16NY was manufactured up through the early 1990's.
I have a Martin cataloge that shows the last 0-16NY and by that time the slot head was gone.
Here is a 1992 Martin 0-16NY. Look closely at the wonderful straight grain in the wood. It is a beautiful instrument.
