The milled seatpost has the small size Campagnolo type- 1970 at the latest, well before Superleggero - Post mfg milling.
I am not afraid of it, the value is diminished as scratched up from insert and removal. Still plenty of life. And it never rains in California...
a slather of grease below the exposed flutes is the way it was done. I could use a seatpost of this era for a 1968 bike.

the front mech is early, but not first Gen.
there are no backside screw retainers.

the Record rear mech has possible original pulleys but they are wasted. Save the bushings- there is a guy planning a refurbish using the mechanical cores and machining new plastic.
