But the 7348 is in the MetalMast's Performance series. They didn't start to phase out the Traditional series and replace it with the Performance series until the mid 80's, which would have only affected the very last of the 323's production run.
Since Dulcinea is a 1978, it has the Traditional series mast.
At one point, I took a tracing and made measurements to determine the exact model #, but when I went to look for it I couldn't find it.
I'll post it when I do.
