Quote slidertogrid: "This is possible, some early Thorn 3000 sets used an A55 120X Which has rounded corners like the 19 and 25" Screens.
Why they would go to the trouble of tooling up to make this when the A56 must have been on the drawing board is hard to fathom unless the square screen posed manufacturing problems...? It couldn't have been in production long I did not see many, and all were made by Mazda (and usually flat!)."

The reason why Thorn persisted using the round corner 22" colour CRT was because Mazda was signed up to using RCA patents for the manufacture of shadowmask CRTs.
The square corner A56-120X was an European tube developed by Philips or maybe a joint project between Telefunken and Philips.

Yes - because of this tie-up Thorn sets used to look quite dated around that time. The 19" 8500 looked old when alongside the 20" offerings from Decca and GEC, both of which also used pincushion correction transductors so the pictures were squarer.
The first 17" 8000 (Ferguson 3712) did look quite American in cabinet design as well, though that may be a co-incidence.
