Thank you Walt.
For those interested, LLH was the trade mark of
Laurent Lochet-Habran, a Belgian barrel maker. Sanderson Bros. is reported to have purchased brls from LLH. Sanderson was purchased by Crucible Steel Co. in 1900 and Crucible also acquired Halcomb in 1911. The 'LLH' mark has been found on Fox, Ithaca, Baker, and Hunter Arms Fulton "Ranger" for Sears guns. Smith guns so marked have been identified as early as 22', and the latest I've seen is a 48' .410

This is Walt's 2E NID with what I believe to be the
J. Delcour-Dupont 'Crown over D', also found on Smith and Fox guns. Others have suggested Didier works in France.
