You did. Sudbury Town has _always_ had roundels with a serif font;
they've been there since the station was built, and considering that it
is now listed, ripping them off would be a Bad Idea ;-)
Silly me

I was very struck by it last time I was there, and had
never noticed it before.
They must have at least repainted them though, I'm sure some rust
patches disappeared. And the roundels in the windows of the waiting
rooms had definitely been changed - you could see the frames of the
old ones, behind the new painted-on-a-white-metal-square ones.
