It appears that there may exist at least 3 possiblities on a longarm with the "SB&Co" stamp:

1. Ithaca, Hunter Arms & Lefever all sourced their tubes from Belgium thru Samuel Buckley & Company.

2. Hunter Arms & Lefever sourced from Sanderson while Ithaca sourced from Belgium.

3. The stamp "SB&Co" is time dependent and after the McKinley Act and prior to WWI Ithaca, Hunter Arms & Lefever sourced their tubes from Sanderson Brothers, a facility under the Crucible Steel Company of America.

I believe almost all fluid steel tubes were crucible.
Walt can you interpret the elements noted with the percentages from the legal pad?

Phosphorus
Sulfur
Silicon
Chromium

Vandium?

Kind Regards,
