Hohner HW-12 12-string acoustic guitar serial number info

Hi there!
A friend of mine owns a Hohner HW-12 12-string acoustic guitar with a serial number 03022460 and he wants to sell it so he’d like to get as much info as possible about the guitar itself. Can you also tell us how much did the new guitar cost back then?
Thanks a lot!

Have a great day,

Hey Gogy,
Have you checked our list with information on histrical guitar models on our web site? Guitars
There is some information on HW-12 (including the former price) on page 14.
From the serial 03022460 we can decuce that this model was made in 1993 (I see that this information contradicts the facts in the list, but might be one of the very early ones?).

Best regards,
