Wonderful to see Eddie coming right along so nicely!
Saddle -
My recollection is that they came through with a conventional leather one at this time. Brand would be either Ialia or Rosa. Their tops were not the equal to topline Brooks or Tron et Berthet products so they did not last through the years. (May have been private labelled "BIANCHI" in some casses.)
Brake lever rubber -
Count yourself most fortunate that the hoods are in as good a shape as they are. Treat with 303 Protectant. The blue hotstamp was eliminated in 1977 so even if one paid the premium for genuine Fratelli Pietra replacements (produced by Atalanta Comma) it would be very difficult to find the blue version. None of the modern reproductions have the blue stamp and their colour is different as well. Replacements for the black adjusting barrel covers are readily available online. The gum ones would be inappropriate.
Toe clips -
Cornez is an italian brand not oft encuontered. My experience of them is that their plating durability is not the equal of Christophe or Allara (Al-E). If you wanted new looking ones that were of italian manufacture and contemporaneous with cycle REG, Balilla and Allara would all be good candidates.
