1910 / 350-only
That's beautiful, Pat. I'm curious about your interpretation of those date stamps.
Do they pinpoint the exact month in 1910 when the 350-only series began?
Or do they tell us only that the 350-only series had begun by June 1910 at the very latest (per the first ledger page with the AB 350 Willett and the June date), but possibly before?
And perhaps some 350-only backs began before or after others (per the second ledger page with the Cycle 350 Dygert and the July date)?
