WYPTE London seat patterns

[ecwfan]

I have always had an interest in bus interiors and i am wondering howcome only WYPTE had London style interiors whilst no other companies had this style of interior.
I mean nearly every PTE had their own interiors but WYPTE copied London Transport. I also think Glasgow had NBC interiors on some buses too.
