Three mice in a hole - possibly Kelso Pottery - Kangaroo mark? Australian?

I would be appreciate your comments regarding this item. Don't know how to name it. It looks like an old style pottery kiln with three mice inside, crouching side by side and looking outwards. There is an incised mark on the base which has been filled with glaze.  
Height: 15cm
Width: 12.5cm

The mark is a little bit like Kelso Pottery

I think you could be right, Naomi. It appears to be a handbuilt animal model by Elizabeth Hird and based on the Kelso Onion. The mark is incised and not the usual impressed mark hence the difference.

I sent an email to Kelso Pottery and they informed me that unfortunately it is NOT one of theirs. So it is back on the unknown shelf.

Looks like a kangaroo to me ....... Australian?

Richard Brooks used a Kangaroo stamp in Australia. He trained at The Leach Pottery St Ives in the early 70s before moving it to Australia. He passed away last year,
