I'm trying to identify a set of blue willow china. My mom had a set that was "lost" before she died--I'm trying to find a set like the one she had. My understanding is the set she had was brought back to the States after the Korean war (so from Asia somewhere?).

The set I'm looking at is a 53-piece set. The back of the china says JAPAN. The box says mpassa 10893-12-m1952. It is the traditional set with 4 people (1 in boat), tree leaning over bridge, etc.

Any help would be appreciated! It's truly a sentimental desire to find a set like the one my mom treasured. (I have 1 sugar bowl from the set and that's it.)

THX in advance for whatever help you can give me.
