Bunny/cabbage Covered Pot w/ CS LO pottery mark on bottom

The CS is above and the LO is below there are 4 bunnies emerging out of the cover and the whole pot looks like a cabbage with a cabbage leaf plate under the pot. I found something very similar but glazed and colorful. This pot is white/unglazed. Trying to figure out who made it and how old it is.
