It is either a Guild
GAD-40C or if it has a Fishman Matrix pickup it is a
GAD-40CE.
In any case the exact model number is written on the left side of the label. You probably find NAT behind the model number which identifies the "natural" top color, means it is not a sunburst.
The guitar case is also the original GAD style case from Guild.
Example of such label:

Bridge: Indian Rosewood Pin Bridge

The first series of GAD guitars, where your guitar is from, were produced between 2004 and mid 2011.
Afterwards they got a new numbering system (3 digits behind GAD) and that second redesigned series of GAD guitars were produced from end of 2011 until 2014
By May 2015 the series was again redesigned and introduced as Westerly Collection line without GAD in the model number anymore.
GAD guitars and the Westerly Collection guitars were and are made at
Grand Reward Education & Entertainment (GREE) in Hui Yang city / China.
The year of manufacture can be found out from the internal manufacturing number and not from the serial number on the label.
All GAD instruments are stamped with a
10 digit internal manufacturing number located inside at the base of the neck block. This number embodies production information about the instrument.
As an example, I'll use the number in the picture below, 1309200096.
The first two digits of this number identify the production year. In this case, 13 would stand for 2013.
The second two digits identify the production month. In this case, 09 would stand for September.
The next two digits, 20, are of no significance and are an internal number used by the vendor to identify their order number.
The last four digits identify the unit number of this specific order. In this case, 96 would stand for the 96th instrument made to the 20th order.
Hope this helps.
