Hello Mike,
Measured with vernier calipers - tube outer diameter - 26.9mm - so I would say it is 27mm.
Upon closer inspection, other than being a bit bent, it is an authentic superstructure.
Let me know if there is anything else that you need.
Regards, Richard

The best method is to use vernier calipers. A ruler is no much good for measuring diameters.
The pipe in that frame appears to be a odd "in between" size . The sizes available here are nominal 27 mm and 33 mm diameter.
