Late to the party again.
Dave asked about the Smith LRWF guns.
"Long Range Hyperbole" was published in the
DGJ by Drew Hause, James Stubbendieck, and J. David Williamson, Volume 24, Issue 1, Page 137, 2013.
I have Dr. Jim's "Production Records" and could answer specific questions. There was a total of 2,704 LRWF guns manufactured, but a few did not have 3" chambers.
BTW: the Parker "Long Range" appeared in the 1894-1895 Montgomery Ward catalog
May 1922
