My cousin has a similarly carved Liege rabbit eared double marked "Moore"...another Pieper based trade name..
PeteM,
Given the period and what we know about the Liege double industry, my guess is; that it is genuine damascus (crolle type)...it's the damascus Schilling linked in post #2 by John Mann, that I would like to know more about. Is that re-twisted wootz or Rigby damacus?..I've seen it labeled "silver damascus", I assume because so much of the black was etched away...
My guess is Rigby horseshoe twist (based solely on observations of early Joseph Harkoms and an English Mortimer)...but how it got to Schilling, I can only guess. Is there a general consensus of what this type damascus/twist steel this is?
