Drew,
Thank you for posting this info. As a Machinist, I really appreciate the pictures and explanation of the machining operations involved in the making of these guns during this period (1907=Minier). Even the discription of the Power Plant (Water Wheel). A very well written piece from the period.
John

Yet another piece of history demystified by Dr. Drew (w/lots of talented help). The next time I pick up a double from this period, I'll be looking for this article to help me understand just what the previously unknowable barrel marks actually mean.
When you consider how the mists of time have obscured most of this information until now, this is a fairly remarkable achievement.

Thanks for this posting. It allowed me to identify the maker of the barrels on my Ithaca.

Just to remind everyone, the 1918 Sears catalog states the Hunter Arms Fulton Gladiator barrels are made of a high grade carbon steel, having a tensile strength of 85 to 95 thousand pounds to the square inch.
The LLH mark of Laurent Lochet-Habran has been found on L.C. Smith Royal, Armor, London, Crown and even Nitro Steel barrels (on an Eagle Grade) from 1914 to 1948, Hunter Arms Fulton and "Gladiator" & "Ranger" for Sears, and also Fox, Ithaca, Lefever, Crescent and Baker guns. This figure may therefore reflect the strength of Belgian rough forged tubes used by most U.S. makers.
Bro. Walt provided the information that A.P. Curtis, General Manager of the Ithaca Gun Co. requested composition analysis and tensile strength testing on a section cut from a barrel made in Belgium performed by E.J. Stormer, Racine, Wisconsin in 1919. Tensile strength was about 70,000 psi, which fits the composition analysis showing it to be AISI 1030.
A c. 1925 Crescent Fire Arms Genuine Armory Steel barrel with the 'LLH' mark was Rephosphorized 1040.
I would very much like to do composition analysis on more barrels marked 'LLH' if anyone has an about 2" chunk they would like to donate!

Drew: I had never heard of a "Fulton Gladiator" before so I did a quick search. Wow(!), enough info out there (mostly sourced to you, of course) to start an entirely different thread on that one. Even Ithaca marked guns! I never knew there were so-many Fulton variants.

Sure did Drew. What's the story on Ithaca marked guns?
