Sorry folks for the long delay. The brand of whiskey is Hunter Whiskey distilled by Seagrams (distillery permit # D-126). I discovered by first researching different types of horns that looked like the horn in the logo, and found one that matched (besides the post horn). So-called "signal horns" or "hunter horn" are used during fox hunts, with an example shown in the attached pic. Also note the riding crop held by the rider in the foreground. The crop has a long whip and handle that is just behind the riders right hand. Although the handle held by this rider appears to be more like a golf putter, other riding crops I've found have a distinct T-shaped handle, similar to that shown in the whiskey logo. Putting all this together I took a guess at Hunter Whiskey, and was correct. Next searched old whiskey ads on ebay and other sites and found Hunter Whiskey dating to the mid 40's into the 50's. The Hunter Whiskey logo features a hunter horn with crossed riding crops (crossed riding crops is a logo in itself used by many riding clubs), one crop with a long whip (the one that looks like a musical note in the whiskey logo) and the other with a short whip. Both crops are common in fox hunts, and in riding sports in general. The hunter horn with crossed riding crops wasn't adopted by the Hunter Whiskey brand until 1948 (at least as far as my research revealed). The bottle shown in the attached pic is from 1948. Early ads (1945-1947) don't have the logo.
