Actually you have a very easy one to date....Just so happens that your Haig bottle has a shoulder label bearing dual locations on it,
and this was only done durring late-1950 & early-1951, when the company temporarily had 2 locations while moving it's headquarters.
As for value, this often sells for about $50...I have several of these myself, some dating back to the 1930's: Never saw one with a
New Brunswick liquor stamp !!
