Robin Welch Bowl Age Help Request

Hello,

I wondered if anyone might be able to help me to roughly date this piece?

Thank you...

It's part of his early standard ware range

What 'standard ware means, Is that for several years after he started his Suffolk pottery in 1965, he had a team of assistants making uniform pottery in thrown, jigger and jolleyed techniques. This produced a substantial amount of identical items, over a fairly wide range.
           So pottery with this sort of mark on is probably not made by Robin Welch himself. But by a person in a team of potters. In a similar way that an item labelled Bernard Leach St Ives standard ware was not made by Bernard Leach.
Below is a link to page 4 of our Robin Welch thread. Scroll down and she will see a photo of a leaflet advertising the types of Stadard ware they mase.
