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.

Whole item photo, please.

Hi Bartholomew,
Thank you for your help so far. Any idea what the number “XII” means in #2? I am attaching the photo for #3.Also, any ideas about #1?

#2.

“Since your spoon is not marked “A1” or “XII” for silverplate, it may not have been silverplated.”

“The company of Rogers Broadhead and Henry Atkin was said to be dissolved in 1853 and Rogers Broadhead set up another partnership named “R.Broadhead & Co”. It seems Rogers Broadhead left the new partnership in 1860 but one of the partners “Benjamin Grayson” carried on the business and the mark “Broadhead & Co” was still used on some products.”

BROADHEAD & ATKIN
