Teapot Blue No Maker Marking Grape Bunch Finial on Lid, Twig Handle, Hunters, Dogs, Horse Pictured

All one color, light blue.

Mesures about 5 inches high, about 7 inches long.

Twig shaped handle with small grapes and vine.

Grape bunch finial on lid.

Grape vines with leaves and grape bunches around top and around lid.

Pictured in relief on pot: one side a kneeling (hunter?) with  rifle and dogs behind him.

Other side, shows man holding reins of a horse, the horse, a boy in back of horse, two more dogs.

Removable round lid has single small hole through near finial on top.

Inside is also same color light blue. Inside has 7 irregular holes inside spout.

Spout has grape vines and bunch of grapes at top of spout.

I find no markings or stamp to help solve the mystery.

Apprecaite any insight as to possible manufacturer, possible date range, country or origin or use.

Have found nothing like this on many sites and none in two teapot books so far.

I got it at a yard sale and the seller had no information, only suggested the handle and finial were distinctive.

Many thanks!
