I need help identifying inherited family teapot

I inherited this teapot and would love to know something about it, I currently know nothing other than it is made of sheet silver and the handle is made of ebony or black wood and it has been in my family for many generations.

The photo of the hallmark is oddly colored from changing the contrast to make the marks more readable.

The castle is nice and clear, the other mark to the right almost looks like a defect, but the edges seem to defined to not be intentional. I am guessing that it is a poorly struck hallmark, any ideas?

Thank you for any part.

Left mark is Hamburg and the letter W? could identify year of manufacture. I am not an expert upon Hamburg marks but to my knowledge this Hamburg mark was in use “Mitte 18 jahundred” as Rosenberg says. That means that your the-pot is approx 250 years (250+) - is that corresponding with model? I would say yes.
Also the use of eberny for handle - so congratulations you have an old germans the pot from Hamburg - no idea of maker.

The term “sheet siler” is unknown to me - what do you mean?

Thank you both for the information.

By “sheet silver” I mean that the pot is fabricated from silver sheet metal, it is not cast.

It being from Hamburg would explain why I was unable to find the marks, I was looking at US marks.

Who is the Rosenberg that you are referring to?

I am used to seeing multiple marks on silver, such as maker, location, date and quality. Why does this piece not have it?

Was this common for this period or area of the world?

Thanks

Different contries different regulations. - in Denmark first regulation in 1429. almost 600 years ago. A lot of fine danish silver carry only 1 mark.

Rosenberg is the german silver book. He selected silver marks long ago. 3 (4) books from beginning 1920ties.

As I am not english I still dont understand the term? I think you are wrong - try to clarify once again.

Thanks for the follow-up.

Good to know that one mark on the piece could be acceptable and not necessarily a sign of a forgery or something else wrong.

By saying the pot is made from “sheet silver” I am trying to convey how it was made. This tea pot is not cast (melted metal poured into a mold)

It has been made from sheet or flat plates of silver that were bent, shaped and formed (fabricated) into the teapot shape. I am not sure if it even matters, I just wanted to make sure it was conveyed how it was made, if that was important.

Thank you again for all of your information, it is greatly appreciated and has help me immensely in figuring out what the tea pot is.
