I have the same guitar in red.
After looking in a hohner pdf with all guitars listed I think that the ST METAL S model matches this model the most, I’m not a hundred percent sure though.
The description reads as follows:
Period it was made: 1986-1990
Description:
body: Californian solid maple; bolt on Canadian rock maple neck; Indian rosewood fingerboard; 22 nickel silver frets
colours: black, pearl red, white with black cracked
3 Select designed by EMG; 2 single coil size; 1 humbucker size;
vol/tone; 3 mini switches: on/off; push/pull for Vintage-Blend-Sound;
black hardware; graphite nut; deluxe machine heads; USA-Wings strings
I hope this answers your question!
Cheers,
