Good afternoon and thanks for accepting me into this forum.
My query is,I am looking at a 1981 grey prolink,frame number.SC062302539,engine number ,SC03E2305453,the bike has 4400klms on it and was registered in 1997 after being parked up from New,after any information on build date or approx value
Thank you.

Build date is around March 1981. Serial number, together with relatively high engine serial ( >5000) indicates an ED= European direct sales unit.
