Yamaha FG-180 Nippon Gakki

[monoBEAR]

i just bought a Yamaha FG-180 Nippon Gakki today and so far i am really loving it. the action is a bit too high for me but i plan to get it lowered a bit in the next few days. my friend works on guitars and is gonna do it for me.

i am trying to find out first off what year mine is and what the difference is between the red label and the tanish label. mine is the tan label. the back of the headstock says Made In Japan and the label says Yamaha Guitar FG-180 Nippon Gakki. also the truss rod cover says Reinforced Neck and has the small Yamaha sign. dosen't say Yamaha. from what i have heard the Yamaha guitars have two serial numbers. the only one i can find is 586978 and it is up inside the soundhole at the bottom of the neck.

can anyone tell me anything about this guitar?

thanks in advance!
