The mystery unravels a bit...
After cleaning with soap and water a silver hallmark has appeared.
According to several sites, the silver hallmark is from the Gorham company. My mark has the lion facing towards the right which indicates that it was made after 1853. Further dating is a bit more tricky. The markings are as follows:
Gorham hallmark
STERLING
K O T
For reference I used Gorham: sterling silver marks, hallmarks, dates and history and Gorham: sterling silver marks, hallmarks, dates and history.
So what does the K O T mean? Is it a date code? If so, the "K" would indicate 1878, the "O" would indicate 1882, and the "T" indicates ???. So maybe it's not a date code in which case if no date code is found it could possibly indicate a date of between 1933 and 1941 due to Gorham discontinuing the year markings between that time period. Why would a piece have two or more date codes on it? Could the KOT be a marking from a plating company such as gold plated silver? My research continues.
In case anyone was wondering, I found this SR back in the late 1970's or early 1980's in the woods in Lutz which is near the Tampa Bay area of Florida.

I found an old post from 2006 on this site from a member that has a silver scale SR. I mention it due to his only having one pin in the scales as well.
