The thing about the Reilly's is that the firm prided itself - indeed it was part of its marketing model - on delivering bespoke guns in 2-3 months vice 2-3 years. I always speculated that to do this, they stockpiled barrels and actions, which would require a storage capacity and a commitment of financial resources. So, perhaps the two A&T barrel sets from 1874 were actually bought by Reilly circa 1866. But I can't explain the 1878 gun with a patent use number that should be numbered in 1882 per the graph.
