Fielding Handpainted Plate

Hi, I have what appears to be a handpainted plate with Fielding 10A2 impressed into the back. Other markings on the back include MM underlined with the letter Y beneath the line in green paint and the letter B in gold.

The front of the plate is a landscape scene with a lake and mountains in mainly pastel colours. The plate has a gold rim.

I have inherited this plate and I know nothing about its history. I am assuming it is early S. Fielding prior to Crown Devon but I could be totally wrong!  I would like to know what it might be worth prior to selling it.

Thanks

Good
