General Comments:
The Style 42 Martin guitar (000-42, OM-42, 00-42, 0-42) is a spruce top, rosewood body
Martin guitar that is a step below flagship of the Martin guitar
style 45 line. Essentially the Style 42 is
a water-down version of the Style 45, with only pearl trim on the top
(and not the back and sides like the Style 45). Still the style 42 has
awesome sound and incredible workmanship and pearl/abalone work.
The Martin style 42 was not originally available in the D body size
(though Martin did make a D-42 starting in 1986, but I hardly consider
that a "vintage" Martin). The OM-42 was only made in 1930 with extremely
low production (the OM-45 really overshadowed the OM-42).
The "42" portion of the model indicates the style of the guitar. The letters before the "42"
indicate the body size (0-42 being the smallest, 00-42 being larger,
and OM-42 and 000-42 being larger still). The models OM-42 and 000-42 is regarded as "the best" size
as applicable to today's musical styles.
But all the Martin style 42 guitars are interesting, as they are beautiful instruments.
Note when refering to the number of "frets", this means the number of frets clear of
the body (not the total number of actual frets). This will be either 12 or 14 frets
clear of the body.

body style and size was not stamped into the neck block above
the serial number, so the body size and style number are
hard to determine on pre 10/30 models):

use the serial and style/size numbers.
This is stamped inside the body's sound hole on the neck block.
