Aside from that I think you're doing just fine, especially if the PIA was in your comfort zone.

I think there may be a timeframe gap between when frame was built (looks just like my earlier than '86 "Cyclone Super Record Export", built with Ishiwata 024, yes 24 not 22 and also has over-BB cable routing) and when that Ishiwata fork MIGHT have been built. But not necessarily done post-market

To my limited knowledge the frame seems like it SHOULD have had the more conventional (as in with forged offset crown and blades) not this slightly "aero/Unicrownish style" chrome fork.
But that's purely IMO and best taken with a grain of salt.

Andy Muzi agrees with you. He said if it was the original factory choice it should have the serial number stamped on the steer tube, which it does not. It *is* period correct, and much like other unicrown forks available, but it was not put together at the 3Rensho factory (probably).
