I purchased the first 2 pieces below some time ago, so I could get to know the characteristics of the pottery, and have a back stamp for future reference.
The designs are not quite as sophisticated from a design point as Lapid Pottery is, but BH has a uniqueness about it, and you can come across some stunning pieces from time to time. It has quite a "chunky" feel about it too.
From the pieces I come across, It is usually (but not always!) characterised by brown - Autumn tonings, and quite deeply carved patterns.
The output of this Co-operative pottery seems to have been quite prolific, and while most of what you find for sale are vases of all shapes and sizes, you can also find figurines and wall plaques - mainly in muted tones, having a very similar style to Joghus Pottery from Denmark.
The two images below are of Beit Hayotser I found on Etsy - and seem quite uncommon designs - but they're great.. Very modernist.
