DC mark - Potential early Derek Clarkson - Thoughts or alternatives?

So I have come across this beautiful large vase, and the only id I can come across is a similar base and paint mark for "Rossendale Pottery - Derek Clarkson"!

Not entirely convinced - but the same type clay, mark and base - so I wondered if you had any other thoughts - as I appreciate most are stamped opposed initialled.

Greatly appreciated as ever.

This is an example I have of Clarkson’s Rossendale Pottery; doesn’t strike me as quite the same style.

No. Derek Clarkson's work is stoneware in a David Leach sort of style, or absolutely beautiful crystalline work. This is just not his style

The suggestion is it’s his early Rossendale Pottery, which was red earthenware before he switched to stoneware. I think the jury’s still out as there’s very little of such work around, or at least identified as being by Clarkson
