Daion Performer Stratocaster questions??

Just bought a Red Daion Performer Stratocaster with maple neck/fretboard, fitted new strings and lowered the action, I think this is a keeper for me.

Came with Pignose Gorilla TC-35, 35 watt amp which requires some contact cleaner spray in one of the pots and it will be good also - Paid $60AUD for the pair.

Very good condition only a small shallow 1cm scratch on the top of the top 'Horn'. - EDIT: Wasn't a scratch at all because it wiped off with a little effort:-)

Cant find a Serial number anywhere, even looked inside the Tremelo cavity on the back, however there is a small gold foil made in Korea sticker on the back of the head stock, any help on the age or where the serial number might be would be appreciated - Seller said he had it for about 7 years, he bought it second hand and thought it might be 20+ years old.

Appreciate any assistance.
