large lidded jug ID with PM mark - Mead Pottery?

Can anyone ID this lidded jug? Thanks.

I've seen pieces with this mark listed on ebay as Nic Collins or Joss Hibbs of Powdermills Pottery but I'm not convinced. Collins usually signs the base too, and this coffee pot looks like a 70s design. There is also Peter Mossop, but I haven't seen his mark in a triangle.
It would help to see a photo of the base.

Powdermills Pottery mark for comparison; there are small but significant differences between the two marks. And it's not Nic Collins' style of handle or neck.

Could that be a DM?

David Melville crossed my mind but his mark has been pretty consistent since he began potting

Another example here, from a jug which was sold as Nic Collins Powdermills Pottery and can be found on a Google search. Handle and neck dont look right for Collins' work and it's not his Powdermills pottery stamp, however he wasn't the only potter at Powdermills

Here is a photo of the base. My original thought was that it might be David Melville.
