Powell Pottery Llangollen 1952

I have a small 4" bowl that is signed Powell Pottery '1952' Llangollen on the bottom. I haven't much info on the piece. I think that Powell Pottery was opened in Llangollen N Wales around the time of this piece so, it may be one of their first. It is a bit primative, made of red sandy feeling clay with a sky blue glaze on the inside of the bowl. The blue glaze is also applied in a crude design around 1" of the outer edge. The disign is a series of 3 vertical lines and a circumpunct alternating the circumference of the bowl.
Has anyone had any experiences with this pottery or the studio? Know when it existed or where I might find out about this piece and the artist.
Thank you

It's not much, but there is (or most probably was, my Gooden is a '96 edition) a Llangollen Pottery. They were on Regent Street and started in 1951, making earthenware by hand. The studio mark was Llangollen in script above a symbol comprising an upside-down crescent with 2 short vertical lines below, just in from each edge (like a cross-section of a shallow bowl on two legs).

Thanks for the info.
From what I have gathered so far, Powell Pottery changed it's name to Llangollen Pottery in the early fifties and that was when they started using the symbol you described. On this bowl, Powell Pottery and Llangollen are in script and the symbol isn't there just the date 1952 with a little dash before and after.
If I can take a picture and then figure out how to post it, I will.
Thanks again,
David
