Friction shifting 7 speed... Super- Recod or C-Record ?
I am putting together a late 80s Casati Monza with Campy gear. I have the following components
:
C- record hubs and Omega Strada V rims
2nd gen C-record headset ,
C-record brake levers
Chorus Monplanar calipers
C-record 1st gen seatpost.
Nuovo Record Crank( for now)
Nuovo Record shift levers
Cinelli 1R sten and Cinelli Bars
So I'm trying to decide if I should go with a Super Record RD or a 2nd gen C-Record RD? Looking to see if there is any preferences from those who've used both. I would likely eventually go to C-Record (doppler) shift levers if I went with the C-record RD. Being period correct isn't critical to me and I do prefer the looks of the Super Record.
Will the original NR levers and Super Record rear allow for 7 speed capability?
Thanks for your input.

If you're sticking with friction shifting, the NR shift levers should work with 7-speed freewheels or cassettes and an SR rear mech. C-Record v2 rear mech should also work with the setup you propose.
If you're using NR or SR rear mechs your best bet is going with small cog freewheels or cassettes and with the shortest possible chain. NR/SR/C-Rec v1 rear mechs like corncobs and tight chains.

I would myself use as long of a chain as I could get away with, and forward axle, so as to allow the top pulley to come up closer to the "compact" cogs.
This will improve shifting response to the degree that this is possible with these old-tech RD's. This becomes more important when using modern (i.e. bushingless and thus more-flexible) chain.
I've set up Campy RD's with large cogs and did then have to shorten the chain to make clearance (chain gap) between the top pulley and largest cog.
As far as I know, the Super Record and C-Record rear derailers have similar body and cage geometry, and should thus both work similarly, though I believe that most of the C-Record era RD's have a moveable B-pivot tensioning spacer block that may allow you to position the derailer body forward and closer to the cogs.

SR will shift up to 28 in the back, and will be less pricy than a C-Record 2nd gen RD.

I have this setup on a bike now, and I really like it. Two other bikes use NR and Victory rear derailleurs with 7-speed, 14-28 freewheels. One has Triomphe dt shifters and the other is Shimano 600.

2nd generation C-Record shifts better than Super Record based on my personal experience.

I am recalling using one of the C-Record derailers four years back on a Calborne-branded Colnago, with an 8s, 12-28t cassette (minus one small cog) and the friction shifting with modern chain was really, really good. I posed with it before handing it over to the owner.
