Is this CL vase Steenstra?

We will never know the answer for sure, but I wonder if this vase on TradeMe is Dan Steenstra's work, the shape and the frills around the top are so similar to the vases he did for Peter Lowrie.

Apart from the 1970s-style textured band around the green one they're almost the same aren't they Val? Since we know Dan was working at both potteries during the time periods they were respectively produced, I would say its almost certain they are his work.

I had assumed that 'Hand Potted' was Shufflebotham and 'Hand Crafted' was Steenstra and maybe other (later than Shufflebotham) hand throwers. But this and a few other similar examples have led me to change my opinion.
I wonder when they changed from 'Hand Potted' to 'Hand Crafted' - or if both marks were used at the same time. Another question that may never be answered!
