N(Old)BD – PX10, I think?

Picked this up for €100, birthday gift to myself. Ride is buttery smooth.

Seems to be a genuine PX10, from around 1975, albeit with some additions over the years. Trying to ID all the parts, here's the list so far, let me know if I got anything wrong or if you can ID anything:

Sakae Road Champion drop bars
Paul Duplex dual pull brake lever
Chain wheel unknown 47t
Freewheel unknown 18t(?), suuuper quiet
Brooks C15
MKS Sylvan pedals?
Stronglight 93 cranks?
Novatec hubs (not sure of model)
Rims unknown
Brakes Shimano something – these are the first thing I will change, but they work fine for now.
