Royal Worcester Wash Bowl and Jug

I'm new to to world of collectible porcelain and I am struggling to find the manufacturer of this bowl and jug set. The jug is about 10 inches tall and has a motif of teddy bears on it with a signature M Hague, my research has connected M Hague with Royal Worcester but there are no mark or signatures on the bottom. I know its old but I don't know how old, my girlfriend has inherited off her late grandmother and she was a collector of china and porcelain.
