The Iron Age, April 1902
https://books.google.com/books?id=xqM-AQAAMAAJ&pg=RA9-PA65&lpgThe first electric arc furnace was developed by Paul Hroult, of France, in
1900. Hroult came to the U.S. in 1905 and Halcomb Steel Co. installed the first electric arc furnace in the U.S. in 1906.
Sanderson Brothers Steel Co. installed an arc furnace in 1907, and the furnace is on display at Station Square, Pittsburgh.
The Horseless Age, Dec. 14 1910
https://books.google.com/books?id=DKONYWNYDqIC&pg=PA813&lpg C.H. Halcomb, former president of Crucible, formed Halcomb Steel Company in Syracuse in 1902, with L.C. Smith as Chairman of the Board of Directors.
Crucible bought Halcomb in 1911, but the company continued to market many tradename steels and steel alloys including Dreadnought High Speed Steel, Ketos Oil Hardening Steel, and Halectralloy Brand Chrome Vanadium and Chrome Nickel steels. In 1917, Halcomb was merged with Syracuse Crucible Steel Co.
John Houchins states that Halcomb supplied London steel for 0 grades and Royal steel for the hammer guns starting in 1907, and in his L.C. Smith The Legend Lives p. 385 has a copy of the 1907 Halcomb catalog with a listing for Machine Gun And Smokeless Rifle Barrel, Revolver Cylinder Steel, and Shot Gun Barrel...furnished in both Carbon and Alloy grades.
The 1913 edition of Halcomb Steel Co. Catalogue and Hints on Steel however contains no mention of steel for gun barrels, nor Royal or London steel.
We have lots of Smiths with London and Royal steel barrels that carry the mark of LLH (
Laurent Lochet-Habran) & ACL (
Acier Cockerill Liege) however.
BTW: The J. Stevens Arms & Tool Co. No. 105, 107 & 115 singles were listed with Electro Steel in 1901; post-1916 No. 105 had Compressed Forged Steel.
The No. 165 singles in 1912 also had Electro Steel.
