Can You Identify a Photo Location?

“Oak room 32 32 GEC Tuesday”

I was wondering if you could help. I have an old photograph that was taken, I believe by George A. Dean, Rugby. The picture shows workers in what appears to be some sort of valve/radio room, written on the back of the picture is “oak room 32 32 GEC Tuesday”.

This request is just to satisfy curiosity and to understand if it was the old wireless works at Rugby as the picture appears to be taken quite early on in the 20th century. Its a bit of a shot in the dark but would be grateful if you could let me know if you know anything about the picture.

 

Thank you in advance.
