VTG Portugal Teapot Pattern # POR3907, Hard to read Maker's name on bottom. I could not find anything to match this teapot, except for a creamer with the same design that's where I got the pattern number. In the second to last photo shows large cracking glaze finish on the teapot. You cannot fill them with your hands that is the way it was finished The teapot is absolutely beautiful. It does have markings on the bottom but I am unable to make out what it says, I did take a photo of it maybe you'll have better luck than me. 6" tall 8" spout to handle 6" Wide 3" base
