Ask UK

Perhaps have a word with the local Council and see if they have any old ones knocking about. They might pass you on to Highways England depending on who's remit this falls under.

It might also be worth contacting a few salvage yards - this one has a lot of street furniture and that includes pedestrian wait push buttons for £35, part of their pedestrian crossing parts section. Although as scrap yards list on eBay these days - pedestrian crossing boxes go for about £60 with one or two up for bids at lower prices.

These look like the people to ask.

That abbreviation was clearly cherrypicked because people wanted justification to name it after a bird. lol.

Anyway, my best guess is to find a mate in the council ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

I hate puffin crossings.

I lived next to the most dangerous puffin crossing in the UK (Whitley, Coventry). This statistic seemed unbelievable at first because the crossing doesn't look dangerous but over the years I came to believe it. I personally witnessed the aftermath of four accidents and was curious about their origin. The way local people used the crossing was to walk up, press the button and walk across, often without looking at the road. There was a time delay of about a minute and as such the crossing was usually empty by the time the light was red and the cars were waiting for nobody.
