Royal Winton Display Sample?

Hello, thank you for any help you could give regarding this. I purchased a box lot and came across this little sugar bowl sized dish marked "Ask for English Royal Winton Dinnerware" the design on the bowl resembles a design Replacements has as number RW127. The lettering is interesting as it looks hand done and is not a maker's mark as we are used to. Would this be called a salesman sample or display sample? and has anyone come across one of these or have an idea in rarity/value? Thanks for any help as this site was highly recommended for the wealth of information you all have. Thanks again, Ruth
