I think that the small symbols might be a signature or maker's mark. The finial on the lid looks somewhat like a pine cone. I think that the design with the little bumps is probably properly called Hobnail.
Measured to the top of the lid but not the finial on the lid, it measures close 5 inches tall. Measured to the top of the handle, it measures close to 8 ½ inches tall.It weighs close to 3 pounds 8 ounces. The condition is much like you see it in the 17 photos after the general description.
Other than some light rust on the outside and some shiny and crusty orange deposits on the inside that might be from making tea, it is in excellent condition with no cracks or chips or dents. It would probably be best to give it a good cleaning before use. A close-up shows tiny irregularities (indentations) in the surface of the handle that I think a probably from when it was made. There are other similar indentations on the handle that I have not provided a closeup of. I see a few very tiny white spots on the outside that I think are probably paint.
There is a little bit of something white on the handle that I do not the nature of. Otherwise, this teapot is generally fine and as shown. My photos should give you a good idea of its general condition. I guarantee this tea pot to be as described and represented by the photos. The photos are part of the description.
Please look at all of them. Please know that the lighting in my photos is uneven and that there are shadows and reflections. N my monitor, the colors are close to but not exactly like the actual colors. Different monitors may show different colors. 17 photos should load with this listing.
