Pair of cups in porcelain de Sèvres XIXth

Pair of porcelain cups. The cups are signed paul blot paris. One of the saucers is marked s.63 for sèvres (manufacture) 1863. They are from the 19th century, napoleon iii. They are monogrammed jc in white on a blue / gray background. They are in good condition without cracks or gins. However, I point out tiny nuanced spots sometimes in the decor (see photos) Cup height: 7 cms. Drinking diameter: 6.5 cms. Saucer diameter: 12.5 cms. Weight of 2: 260 grs. I point out that 6 cups in sèvres porcelain and model are online.
