What is the serial number code for these again?
That's a good question and there is no final answer yet.
SPG used "KS" (Korea, SPG) as starting letters and the headstock shows "KSG" where G stands for Guild.
Now I thought the next two numbers "12" would be for the year of manufacture 2012. The problem however is that I have not seen a KSG13xxxxx yet! All so far shipped Newark St. models start with KSG12 and run in the fivehundred numbers so far. Does that mean all started production in 2012 already? Or is the 12 just for "2012" models, means 2012 designed models? That is something I was not able to find out yet.
The other 5 numbers behind are a sequential serial number independent of model number, so there is only one number 7 for the entire Newark St. collection as example.
So the serial number has no code for the model number in it.
