Canadian Pottery ID

I know there's a fair number of Canadians on this site, so this question is directed primarily at them.
I've been collecting Canadian pottery for more than 40 years and I can nail down most of it but a few pieces ...
I found this MCM piece a few months ago - my guess is that it is Laurentian ("Canada" plus a number "338" on the bottom).
Agree? - Disagree? - Any other ideas?
I call is a Lobster claw Vase? Planter? Very dramatic.
It is 12" high.

 

Maybe you can find some help here,

Is that a white body ceramic? That, in itself, would be unusual.

 

Unfortunately, that site is missing a lot more information than it has. I use it, but 9 times out of 10, it doesn't help.

 

The only unglazed spots are one stilt and a small area nearby. The clay appears to be pale pink. The white spots along the edges are white glaze. One of the reasons I lean towards Laurentian is that they strongly embrace avant garde shapes and glaze techniques but their execution tends to be rather sloppy.

 

Haven't found that color combination elsewhere. So many companies. A more direct side view might help with image search, and photographed against a neutral background. Image searches seem to lean towards color orientation
