Wanted: Campag Record vintage chainset - 170

I'm in the process of gently updating a 70s Cyril Guimard tourer which has lots of heavy original steel components.

I'm looking for a Campag Record chainset to match recent wheel upgrades so thought I'd check if someone has a set gathering dust. 170 length and 39 or upwards on the inner chainring ideally.

I'm new to the game so ask if I've missed critical info.

Based in London so happy to collect or alternatively post.

Thanks for looking

what speed and what era? cheers cc

Got a road double vgc 170s
What's your budget?

@colnago_costa - Looking for a double, it's a 14 speed and currently on 34/52 but I'm not touring so after 39 upwards for the inner. Open to offers on era. I'm trying to respect the period whilst shaving some weight off it. I've not been to age it so far but I think 70s. This is current incarnation:

@m_f - lower the better but open to offers. I've seen stuff on fleabay around the £30-£50 mark but happy to be educated :)

Campagnolo double chainsets up to the late 80s can fit a minimum inner ring of 42*, so you can't get a 39. From the late 80s on (Athena, Chorus, etc.), you can have a minimum 39.

• there are some non-Campag 41 rings, but certainly no lower than that due to the diameter of the arms.
  

@nammonk - thanks for those pointers.

PM'd to follow up on the earlier replies.

Any more offers let me know.

Personally I'd go for a Stronglight 100 style crank
