Wigwam nice centre stands on amazon around £22 look good but legs on 50 inch should fit I’ve measured ! Yes big names being bought out cheaper Panasonics vestel made in Turkey mmmmm but my Toyota CHR assembled in Turkey !!
There are two types of stands that come with TV’s these days, one is a centre stand the other legs that spread apart but, there is normally 2 positions to put them. What would concern me with legs is if as I think your current stand is corner mounted you would have to make sure the legs fitted on. However £22 for a satand on Amazon does not break the bank.
Vestel only make make some of the cheap Panasonic TV’s.
