This cup and saucer have no maker's mark. The saucer has a red script mark 1746. The colors are Imari with the reds and dark blue highlighted with gilded designs on a white porcelain base. The pattern is very similar to Royal Crown Derby Imari 2451. Because it is not marked Royal Crown Derby, I would have to say it Derby style. I have 10 cup & saucer sets available. Nine are without chips or cracks. One cup has a chip on the rim. Several have slight wear to the gilding. 1 cup has tea stains in the cup. The price is for a single cup & saucer. You may purchase 1 or more. I do combine shipping if more than one is purchased. Each saucer measures 5 3/8" in diameter. Each cup measures 2 5/8" in diameter at the rim and 2 5/8" tall.
