F. W.(Friedrich Wilhelm) Kessler(7.26.1845 to 9.07.1919) offered tubes in:
Krupp, generally
Rochling Spezial Steel(recommended for- "pureness and tenacity"
Bohler Spezial Steel
Krupp Spezial Steel
Witterner Excelsior Steel
Bohler Antinit Steel

So yet another offered Rochling. Considering the "Whitworth mark" thread, anyone know if the mill or the tube maker pressed the name of the steel maker into the tube?

Kind Regards,

Raimey
