Thanks for posting this
I have associated the D-9 marking with Old Quaker Whiskey, Schenley's Whiskey and Golden Wedding, Likely this was another brand made by the same company (D-9 is the distiller # assigned to a particular company)
The only way to track this down is by searching for a labeled example - I have spent a bunch of time examining bottles marked "Federal Law Forbids..." on eBay.
