Unknown Caterpillar

[JayJay]

Is anyone able to ID this caterpillar please? I have been trying to search online but so far have come up a blank. It was about 2 inches long and was taken last month in Devon.

It looks like an oak eggar moth or gypsy moth caterpillar but it's difficult to tell

Twitter came up trumps. It looks like it's a Four-spotted Footman.
