Primary chains now establish the permitted physician–pharmacist record system, the 1921 quantity and prescription-blank limits, and Doran’s 1930 manufacturing-allotment snapshot. Earlier secondary citations supply bonded-stock, packaging, custody, and distribution context.
Legal medicinal whiskey during Prohibition depended on bonded stocks, licensed production, physicians, pharmacists, prescriptions, packaging rules, quantity limits, and replenishment authority rather than functioning solely as an informal consumer loophole.
Promotion gate satisfied: complete primary federal sources verify prescription controls and the Doran-era replenishment snapshot. The common fixed-six-distilleries formulation is rejected.
The system changed over time. The January 1930 list is a dated snapshot of eleven concentration warehousemen, distillers, or successors and must not be converted into a permanent roster of six Kentucky distilleries. The 2,000,000-gallon/40,000-barrel figure is an allotment basis, not proof of completed output.
English's account explicitly links inventory, custody, production authorization, professional prescribers and dispensers, packaging, and patients.
The infrastructure interpretation is supported by independent secondary analysis plus exact primary-law and administrative anchors. Publication copy should separate statutory rules, industry custody, and the January 1930 snapshot.
