Zoebisch Sons (Zoebisch was the sole distributor of Martin at the time).
Many of these unique instruments pop-up today and dont fit any clear category.
This implies that a number of ukuleles built in 1930 remained in the factory until being sold in 1932.
This would also explain why the occasional pre-1932 Martin guitar appears with a decal.
Weve found many exceptions to these numbers but they are an OK guideline to the approximate date of manufacture.
On instruments with round sound holes, the label is visible directly inside.
On f-hole instruments, it is visible through the upper f-hole.
The second type of serial numbers used started with an A prefix and ran from 1947 to 1961.

Of course, many of the older guitar builders and craftsmen were still in Kalamazoo; and if they werent ready to change how they built guitars, then they may not have been ready to change how they numbered them Certain guitar models built in the late 1970s can be used to demonstrate the old-style 6 digit serial numbers.
So double check the serial numbers on those 1970s L-5s, Super 400s, and Super 5 BJBs.
In the earlier years at Gibson, guitars were normally built in batches of 40 instruments.
Gibsons Factory Order Numbers were an internal coding that followed the group of instruments through the factory.
Thus, the older Gibson guitars may have a serial number and a Factory Order Number.
