Basso catalogues from 1983 to 1988

Hi folks,

I was wondering if anyone on this forum had scans of Basso catalogues from 1983 to 1988. I only could find catalogues from 1981 and 1990,91,92 online. I acquired a Basso Gap from the year 1987 but the frame was repainted and I want to restore it to its former glory.

Thanks.
