Is this an early Ambrico Experimental??

Along the lines of what we have seen with Manos's vase I bought this pot recently and cannot figure out what number it could be.

I have photographed it firstly beside another un-numbered one, which looks the same, and a shape 42 which is similar, but bigger.

Tell me what you think...

I think the shape is identical to the white vase.....
and the glaze has run off the pot and stuck to the shelf it was fired on.
It could be an experimental glaze piece.

It does look like the white one, but it wouldnt be experimental then would it?? The white one has no marks at all, but is identical to my 134 in decoration. (there are two 134s the same up on trademe at the moment).

I cant seem to figure out what numbers they would be if they had one, and when I see the luxuriant glaze and the ponding at the bottom..it made me think experimental.

At an Antique Shop in Cambridge I saw a pot identical - with a wooden lid...I think my vase may be a sugar bowl....
