Can anyone find me a match for these bricks?!

[TheBrilloPad]

I swear to God I have spent hoursssss googling every online builders merchant trying to find any bricks remotely similar to match these (pic attached) and am having no luck at all.

Is anyone familiar with building materials and know what these sort of bricks might be called, or where I could buy similar ones?!

Seems a long shot but I'm desperate!!

Cottage mixture?

They look like an imperial handmade size/type, not sure on the mix. Could be a grey multi.

Do you have any brick merchants near to you? They are the best people to ask as whoever built the wall most likely bought the bricks locally. We have a brick merchants near here that also hand make the bricks and when I was looking to match they were able to identify the local manufacturer and mix from a photo.
