My lepage Belgium gun has Siemens-Martin steel on top,
LLH , ACL (in a triangle) and I stylized H B all on one set of tubes.
I assume that mean Siemens-Martin made bar, LLH bored tubes, acl put them together and what did HB do?
Or is that incorrect?

Thank you and very nice. HB may be on the bottom rib also, and he was no doubt proud of his barrel work

I believe my 1903 browning a5 had the same HB I will have to look for old pics I just sold that thing last week. Nope just pulled pics, I have seen HB on a barrel of mine before but I have sold dozens of browning a5 barrels many had Cockerill barrels.
Thanks

Not sure if applicable, but Park Bros & Co produced a steel recipe including Tungsten/Wolframite via the Crucible Process packaged as >>Imperial<< Steel. Miller, Metcalfe & Purlin produced a steel recipe named >>Crescent<< steel. Both were analyzed in the 1890s. Not sure if they were still producing it or bar stock by 1905.
Cheers,

It seems highly unlikely that a wolframite or tungsten alloy would be utilized as a steel for gun barrels. Those alloys are used for armor plate or armor piercing projectiles, and would be much too hard and brittle for barrels.
I remember working in a hot mill where a lot of steel that was used for armor plate or fragmentation (cluster) bombs and grenades was produced. The stuff would occasionally shatter like glass even when it was being coiled up while still glowing red hot. Shards would go right through the sheet steel siding at the end of the mill building. Naturally, it was not a good idea to be near the downcoilers when that stuff was being rolled.
The odds of finding out just where Dan Lefever bought barrels marked Imperial Steel are remote at best. Records from his companies are pretty much non-existent. If one of my Lefever guns is marked Krupp or LLH, then I know. Anything that isn't identified is a guessing game. I have a D.M. Lefever that appears to be a 7D with fine Damascus, and an O Excelsior grade with fluid steel tubes. I'll try to take a look at the markings on them in the next day or so.

Thanks
Excelsior should be same steel if not Damascus.
Thanks
I dont think their were more than 1200 of these crossbolt guns made, tuff to find any good info.
Great to hear you have 2. Awesome!
I shot 25 rounds of 1 1/8 international powder 10k plus loads through it today with no problems( yep Im married so what the hell LOL). I will keep them under 10k and use reasonably fast powders. First 6 pit free on pitted side very thick. Think I will skip anything more stout than that.
But would like to know if your excelsior has any proof marks.
Thanks Keith

I will try to take a closer look look this evening Jtplumb. I'm pretty certain that my O Excelsior has no proof marks because the U.S. does not have a proof house. Occasionally we see American guns with proof marks because they were at one time sold in a country with Proof laws.
I do recall that my Damascus D.M. Lefever which appears to be a grade 7 D has a SDG stamp under the barrels. This indicates it was sold through the New York Sporting Goods Co. Shoverling, Daly, and Gales. I say it appears to be a 7 D based upon engraving, checkering, etc., because it is a semi-pistol grip gun and has no grade stamp anywhere. I found it interesting that your 1905 catalog did not list the grade 7 D guns any longer. Based upon the low serial number and the "Not Connected With Lefever Arms Co." statement engraved on the trigger plate, I believe mine is a Syracuse gun built in 1902.

Forgot about the "Pieper Eclipse" (unknown DOM) barrel I had tested. Pieper was reported to use Cockerill steel.
The sample was non-typical (high phosphorus) AISI 1030 with a measured tensile strength of 99,500 psi.
That would be similar to standard 1040 or 4140.
