I have seen an early Waterford Paramount which used the the '60s-'70s Paramount headbadge. It was probably an '81-'82. My '83 has the Rainbow headtube decal. My serial number however, corresponds with the Chicago built ones with a month code Letter, followed by a 2 digit year followed by the frame number. It is on the left rear dropout.

That fork does not match the one on my '83. And my shifter cables run over the BB shell, not under it like the one you have pictured.
