My 73 125 Six Day has 35mm forks. It was made in Oct of 73. Should it have 32mm forks?
Maybe, but I think an Oct '73 build date bike is not a '73 its a '74. Nov '73 is when the 250 changed colors from gold to red, so your bike could actually be a '74, which should have 35mm forks.

the 74 should have black mag hubs but then ?
Yes, if a '74 it should have 35mm forks and black mag hubs, if a '73 it should have 32mm forks and bare aluminum hubs, but you never know with these bikes. As Jack told me once, they would open a new crate of 4 bikes and many times every one of them would be different.

Early 73, 32mm late 73 35mm. Not in stone, KTM used what they had at the time.
