Korean Ibanez Serial Numbers

C = Cor-Tek (Cort), S = Samick(1990-1995), S/SQ = Saehan(Sunghan), P = Peerless (Iida), Y = Yoojin, A = Sae-In.

YY = year (03=2003)
MM = month (01=Jan..12=Dec)
XXXX = production number

Ok but my guitar is made in Korea and this is how the serial is laid out

RX 60
C 5032707

So when was it made and what production I can't find it out.
