Congratulations! With regard to the mysterious Columbia disc record:
All I can say is that it looks like an American pressing.
The Columbia Phonograph Company, General, was staretd in around 1897,
but did not start disc production under that name until 1902.
From 1908 all Columbia discs were double-sided.
Thus, your discs should be from the 1902-08 time period.
The series prefix "S" probably stands for "Siam"
but which number was the first issue...?
