Can you put a date on this Claud Butler please?

[Bobby Maclean]

Just picked this up. I think the derailleur is a gran sport campy?
It’s tricky to read but I reckon this is worth restoring, lovely head badge too.

 

[Drago]

I'm going with 1950's, but could be earlier. Do you have a frame number?

 

[Bobby Maclean]

Thanks Drago.
Nothing on the bottom bracket that I can see.

 

[Tony Raynor]

If that's a Williams crank there will be 2 letters that you can use to date it

 

[midlife]

Any number on the rear dropout?

 

[Bonefish Blues]

What font would you like?

 

[Bobby Maclean]

Wondering if the paint job is hiding numbers, using a spot light to try and get any indentation. There is some info on the derailleur.

 

[Bonefish Blues]

Catena is chain in Italian, so it's chain width.

I'd say 60s maybe even as late as mid-70s. I don't think the pre-Holdsworth ones had the curved brake bridge. Here's the site to trawl through.

 

[Cycleops]

That's very nice and well worth restoring.
I'd say it's early/mid sixties perhaps later but you won't know until you find the number which is likely hiding under the paint somewhere.

 

[Smokin Joe]

Sixties for me too.

The oil hole in the BB might make it a tad earlier.

 

[Drago]

The oil hole in the BB might make it a tad earlier.

That was what I was thinking, though despite being a CB owner I'm not an expert at dating them so it was a hunch.

 

[midlife]

The thing is that grease nipples / oil holes hung around for years so could be a red herring lol

 

[pawl]

I don’t have any dates but have fig you are welcome to.

Looks late fifties early sixties to me.
