e.g.
There's more pattern catalogue scans here (post #13 if you scroll down)
In addition to being a fancy foreign frame, there exists the possibility that 26.8mm can be a plain gauge British frame (e.g. 531 or 501)
To confirm this, stick a vernier to the outside of the frame tubes - if it's 1 1/8" (28.6mm) then it's plain gauge tubing, if it's 28.0mm it's Columbus (or perhaps French 531)
Clear as mud I know.
