I purchased a Yamaha acoustic G-170A in Okinawa about 1965-1967. I'm unable to identify the instrument on the internet and hope you can help.

Five images attached: Image (1) guitar head, Yamana Tuning Fork Trademark (TFT) 
All printing on label (light tan) is in gold. Image (2)

Image (2) Internal label (inside, bottom)

Image (3) at top right of label is a logo(?)on label shown in image (2) -that's the best drawing I can manage :-) the numbers at bottom of this logo are - 9202 - I can verify the first three, but the last "2" is a best guess.

Rest of label: A design (slightly darker tan) covers the oval center area of the label, but I cannot make out much of it. The label gold lettering reads:
1st Line -- (TFT) YAMAHA
2nd line -- G-170A
3rd line -- Nippon Gakki Co. LTD.

Image (4) location of serial number
Image 5) full guitar body and neck

Thanks in advance for your input. Jachor
