I am used to National made bikes having the serial on the lower head tube. But it does follow National layout for February 1984. Faux bi-plane fork, missing original bull moose bars. Putting Fat Franks on it, just for kicks. Ape hangers and Next stem have been removed.
Agreed, it does follow the National format. We know that National did some manufacturing for WSI in the early 1980s and their format has turned up on a handful of Centurion Turbo and Pro Tour models with the S/N being stamped on what appears to be the same BB shell and with the same Made in Japan label. Consequently, it would appear to be National. Here's an example of a Centurion Turbo serial number, BB shell and country of orign label, as submitted by BF member Classtime.
