Anyone with a 731OS frame, help please.

I'm pretty sure the frame I'm about to start on is 731OS
The ST and TT are coming up about 28.8 and the DT about 32, that's with paint.
I've only got 27.2 posts and they don't fit. But that's what the internet is saying should fit.
So can anyone confirm this for me please?

Geofrey Butler team bike frame number 007

Hi,

The interweb is right on this one. I have a TJ Quick 731os frameset, it takes a 27.2mm seatpost.

Cheers Matt

Cheers Matt.
They only made the stuff for a few years, so doubt they buggered about with changes.
The tube dimensions scream 731OS. Dave LeGrys said he had one himself from G Butler.
Oh well, if I cant find a Columbus tube set that size, then it'll have to remain an anomaly.

Update....thanks to Matt.
I've got 27.2 going in and out. Seems it had been overtightened and knocked about whilst laying around.

I'm now convinced that it is a 731OS Geoffrey Butler team bike. The dimensions are now spot on, and the serial number 007 and race number braze on suggests a short run.
Without prompting LeGrys said he had one when he rode for them, and Cliff Shrubb built it for him.
However the Cliff Shrubb boys say he never used 731?
