Need help identifying Royal Crown piece

[lynn in ma]

Hi.  I need help identifying a piece, which looks like either a small jam/jelly server or covered sugar bowl.  It is approx. 5 3/4" L x 3 1/2" W x 3 1/2" H; the base and bowl are attached but the cover is separate.  The markings on the bottom seem to be handpainted:  Royal Crown with a coronet under that.  Under the coronet is 11/446.  I purchased it in a small antique shop in Sturbridge, Mass. about 20 years ago for about $5.00.  Can anyone tell me what exactly it is, if it is English or Japanese and if it could be real or a fake?  Thank you for your help.  I have attached some photos.

With the size it looks to be a lidded gravy boat with attached underplate.

Could be, but to me, it seems a bit small to be a gravy boat.  The piece doesn't hold more than 4 ounces (if that) and the notch in the lid for a spoon or tiny ladle (it didn't come with one) is very small.  Is there such a thing as an "individual" gravy boat, like the tiny individual salt and pepper shakers I have seen?  Sorry, but I'm somewhat ignorant about these things.  Any feedback is much appreciated.
