Here's a police post in York, a nice close up with some signage detail.

I thought you may of stumbled across another Town (or city!) with Proper Police Boxes there limerence........
But sadly not!

Sadly not  These Post types were installed quite widely over the country from what I can tell.

It always is exciting when you see them outside of London, though, because you immediately think of Met boxes. I feel like if a city as high-profile as York had Met boxes installed, we'd probably have some evidence by now, or just anecdotes about them! Whereas if you have comparatively small places like High Wycombe, you're less likely to have anecdotes and things like that shared around - searching the internet far and wide, the only place I've ever been able to find people talking about police boxes being there is on TARDIS Builders. So much history is undocumented that if it wasn't for the aerial photos and the mentions on here, we might never have known there were Met-type boxes in High Wycombe.

That's why I'm currently documenting PCBs in a lot of towns and cities in England and searching for aerial photos of those PCBs, just in case there are any other places where the TARDIS-style boxes were (besides London and High Wycombe). If there's anywhere in particular you'd like me to look, just let me know.
