NGD. H-150cm. Question about serial number.

[MorrisDavis]

Hi all. I just got the lovely H150-cm that was available for sale here recently

 

The inked serial is ABS4102.

 

What does that "S" in the middle mean? If I read the other threads right,AB is year code, 41 is date code, and 02 means it was second guitar made that day

 

Thanks in advance for any help.

I think I've answered my own question. The S is a 3 stamped backwards. The label on the inside of the control cavity starts out AB3...

I looked again. The S is a 3. There go the eyes I guess.
