Looking for a birthday

Hi there I have an old Shark Fin, Serial number S603G I was hoping you could tell me what year it was made.

Is there a longer number somewhere? S603 looks more like a model name :face_with_monocle:

Unfortunately, the HOHNER guitar archive has a lot of blank spaces and this was a rare - but VERY COOL - model. I have data on a S604 and S608 made in 1988. Maybe your S603 version was a kind of predecessor of these two.
