Vintage Royal Mfg. Co. Triple Plate Teapot~Cr. & Sugar

Up for bids ~ from my attic comes an ornately decorated triple plate teapot with matching creamer and sugar. All three pieces are marked on the bottom. The teapot measures 8" and the creamer and sugar 4" each. This set has been in my attic for years along with several other pieces which I will be listing. I am not familiar with this type of merchandise so my knowledge is limited. Overall condition is good but needs a lot of cleaning and polishing. Shows some overall scratching and the teapot finial is a little crooked. I'm not sure if the sugar had a lid at one time but if it did it is missing. Would make a lovely set when cleaned and polished.
