Today in the Taylor-Hay family papers I found a 1937 report on distilled spirits in bond in Kentucky published by Liberty National Bank. Liberty did these reports every year up into the 1990's and may be still doing them today in their present incarnation (I forget who bought who in the banking industry).
These reports are filled with interesting facts. For example in 1937 there 1,071 barrels of pre-prohibition whiskey in Kentucky warehouses. Brown-Forman had 3 (.28%), Glenmore had 7 (.65%), Louisville Public Warehouse had 398 (37.16%), National Distillers had 601 (56.12%), and Old Kentucky Distillery had 62 (5.79%). The other distilleries did not have any pre-prohibition whiskey in barrels in their warehouse. As I look over this report closer, I will report more.
