A Team v B Team Trial Match in August 1952.

There’s a structure on the top of the terraces in this picture. Not sure if it’s the same one?

Ersk, you could be right mate, the base of that floodlight??

Hi Ersk. You posted a while back something on the floodlights and the date when they were installed?

The structure we are puzzling over isn't the floodlight base, although the base of the floodlight midway along the top of the West Terrace was where they used to film from.info below...

"These colossal floodlight towers were erected in the 1950s and 1960s. Because the stadium featured an open, wide oval running track at the time, the large floodlighting columns had to be built with significant concrete bases. These sturdy bases were multi-purpose, often housing not just the electrical equipment but also serving as a structural platform for the stadium's television camera gantries,

The Rising Sun: Cheers for the information. Much appreciated.
