I know that George Lindner sourced actions and barrels were imported into the US and finished/labeled by several gunmakers ( Schaefer & Goelcher for example).
I know of Daly branded Lindner guns that used Lefever patent actions ( sidecocker), but I am not aware of any Lindner or Daly guns “ finished” by Lefever.
I cannot recall reading about Daly ever using Lefever Arms as a subcontractor for any of their import lines.
I would be interested to know how L,S&B came to their conclusions- and why they felt inclined to include that bit of “reference” in the historical trace.
