Help with hallmarks needed

Hello everyone,
I have three separate questions.
#1. Please help with identification. Also, does the letter “S” in this particular case stand for sterling?

#2. I know that the “Chas. J. Dale” stands for “Charles J. Dale” the jeweler who operated Chicago, IL 1885-1895; Plattsburgh, NY 1895-1911; and Oswego, NY c. 1912-1914.
The number “XII” is frequently added to show the thickness of the plating. Not sure if this is the case here. This particular spoon in its quality is resembling a coin silver one.

#3. The third question is about markings on the tea pot. I have searched the internet and found nothing about it.

Thank you in advance for your help in this matter.
