No, there weren't any pre-war Seymours - the company was first registered, according to Iain Wright's Bulletin article (Summer 2007), in 1942. Seymour Products (Ashton), that is, which went into receivership in 1948 not long after Seymour Products (Arbroath) was set up, and that failed in its turn somewhere around 1952 - it's a complicated story. Though they exhibited a TV it doesn't seem that it ever entered production, and just general failure quite to make ends meet appears to have defeated them. The Ashton company was wound up after failing to pay £12,000-odd of purchase tax due to the Inland Revenue.
I've a couple of Seymours here, one a console model like yours - at least half the surviving Seymour sets seem to be of that model - and the other a Montrose table radio.
