As an aside, how is the BB shell identified as Hitachi Developments. Was it literally from the casting mark??

This is great info to hear but to a Vintage newbie a lot to take in and understand. The last few weeks have certainly been a “baptism of fire” into the world of Vintage Steel but I’m pretty happy that this bike is my first foray into restoration and ownership.

That mark is literally the main Hitachi trademark they have/had used for decades, likely the original.
