This is Larry B’s SR Grand Course, complete with some crazy “anodizedish” looking components and some marbleicious wrap.
YR 1980’s? SR/ GrandCourse(i know that for a fact) I sanded it off! I purchase 2 of them off CL and only actually wanted the 58 but the seller would only sell as a pair.They looked exactly alike(rust and all) exept the size 58 & 63. I sold the 63cm to a friend for 30 bucks and restored my 58cm.
