Tough call. I don't know guercs well enough to date the frame, but I will say the start cut-out makes me think it is at least a 1984 frame. The components speak to a build date of 1988. First gen chorus aside from the pedals and the C-record RD... strange they would use the inferior record RD as opposed to the chorus... but then again chorus was new and record is king (you don't question that), but in the end the drop plus slant parallelogram of the chorus made it way better on anything other than a corncob.
