Bay Keramik fat lava glaze ceramic planter pot orange & browns 70s vintage W Germany

Vintage Bay Keramik - West Germany planter pot, browns and orange drip glaze with a little lava (like the vintage Scheurich pottery pieces). Later mid century, probably 70s I think. It's marked 4312 on the bottom.

This measures 4" tall, and about 4 3/4" across the rim of the pot. Condition is very good - no soil, just a few scratches on the interior. No chips or cracks.
