Fiesta Salt and Pepper listing

I was sent this listing and the most interesting thing about it was that they will be earthenware and probably are the Shape 183/184 Salt and Pepper.
We have put the Vitrified Salt and Pepper in the Gallery as Shapes 183 and 184 and now I'm not sure if we have them in the correct place.

Any thoughts Jeremy?

The trademe set is in my Fiesta colourway!

Ev, remember the trouble we had with sorting numbers for the demitasse duos. The conclusion was that until 1960 or so when the new shapes were introduced the pieces with the same shape shared the same numbers regardless of whether they were e/w or vit.

I suggest that that may be the same case here. The earthenware and vitrified condiments shared the same mould therefore they have the same shape number.

Whether earthenware or vit the shape should be correct for the gallery.

Maybe it's the same story with the 755 Carlton cups too, thus the 805 saucer. The numbers for the early (three digit) shapes are not coded in such a way as to distinguish whether e/w or vit. This might also explain why I have seen crazed 715 tankard jugs when they are supposed to be vitrified.
