Value of Noritake Northcliffe China?

I have a set of Noritake dishes from the 1920s, the Northcliffe pattern. It's not a complete set, but you can piece together dinner service for 10-12. It's in excellent condition.

I have:
10 dinner plates
12 salad plates
12 bread & butter plates
5 soup bowls
6 fruit bowls
An 11.5' oval covered dish
A 10' round covered dish
A 10' oval platter
A 9' oval serving dish
An 8' oval relish dish
A gray boat with underplate

Wondering what this rare, antique pattern might be worth?
