Please help me identify this marking

I did my best to try and find out about this company but I haven't found anything yet, I'm just going to make an educated guess and assume the C means company. The crown and shield symbol is very common so that didn't help much. I searched Kovel for a crown and shield symbol like this and I found that J.Kents markings look almost identical to this one. Since J.Kents Longton was a village that he worked out of, I thought that maybe (C)ayde or (S)ayde might be a village in England as well. I looked up both names and nothing came up. I guesses that the letters might be C, or S.

P.S. was it common for potters to have strikingly identical symbols like this, at one point I thought maybe ML & C was a J.Kent copy-cat or maybe they did operate close together. I don't know.

 

Yanna, it looks as if it might be Moore, Leason & Co.
