Replacing shower head

[JamesFMB]

Hello!

I'd like to replacer my shower head, but I can't find a head with the right fitment on the internet, is this a common connector? See attached picture.

Thanks in advance!

James

Looks like a bespoke part from a specific manufacturer

I take it that was a shower arm out from the wall? Do you know who made it?
