fine job with the photos!
the Union pedals are from Germany so they are sure to be replacements. they are a model called K10491/U41 and a bit later than the cycle.
the backside of the Takagi crank arms should exhibit markings. these may include a date.
Takagi trade publication advert of 1971:
Three Arrows is the firms logo.

Great information, piece by piece it comes together! Awesome to actually see the original adverts. When I get a chance I will see if there is a date on the backside of the crank arms or any markings.
