Hi,

I’m struggling to identity this typeface, it is used for the public convenience in central Hastings, I'm intrigued as it is so similar to Trebuchet.

It looks somewhat familiar, but I wasn’t able to find an exact match. The most striking feature is the “cross-less” |t|, also featured, for example, in Ubuntu. But none of the similar typefaces I found have sloped |i|, and very few have a sloped top of |l| (and none has such a shy bottom curve). 

In conclusion, looking also at the rest of the letters, I would say that this is indeed Trebuchet or, rather, a not terrible customisation of it, with a chopped |t| and an |i| modelled after the ascenders.

I can’t say if such thing is available somewhere, or if it was specially made by or for the signmaker.
