egg shaped pink china flower vase for bulb or Easter flowers, vintage Lefton Japan

Numbered (but otherwise unmarked) vintage china vase, Lefton's - Japan? We love the egg shape and the pale pink color, so pretty for spring!

This is about the size of a goose egg, it's 3 3/4" tall, about 2 1/4" across the opening. Perfectly sized for a single flowering bulb, or to hold a bunch of violets or lilies of the valley.

It's 50s or 60s vintage, we think. This is in very good clean condition without chips or cracks.
