Very interesting!

Square-ish aerial transformers seem to be common in many countries outside the US. Virtually all of ours are cylindrical, at least since the 1940s.

In the 1960s GE introduced the "SealPak" transformer which had a shape somewhat like the one in your picture, but I don't think they caught on; at least I've never seen one except in ads.

Do aerial transformers in the UK typically have primary fusing or cutouts? In the photo, it appears that the primary leads are connected to the lines by hot-line clamps, which would serve as disconnects.
