Trying to find a cup for my fiancée, not sure where to ask

So my fiancée bought a cup while visiting London a couple of years ago, before we met. It's her favourite cup, as well as mine. It just feels good to hold (due to size, weight, shape).

So I'm trying to get a hold of another one of those cups, but there is no brand name on it. All it says is "Made In England" on the bottom of it.

Does anything look familiar? Tips on where to post if this isn't appropriate?

Thanks
