No, I don't mean holding hands and going for walks along the harbour side.
With some of the old brands and bottlings I have come across I have found that a good deal of detective work can be required. In order to assist with some of the basics I though a thread might be useful that identifies some key dates for labelling requirements, bottle styles and such. For example: the requirement to include the statement regarding refilling or re-sale moulded in glass has helped me with my detective work on a US brand of Irish whiskey. In fact here it is along with other useful info:

Some regulations that could help date a bottle are:
When did the requirement to state proof and volume on labels begin in the UK and Ireland?
In the UK proof gave way to abv 1 Jan 1980.
When did Ireland adopt abv?
When did volume change from Imperial to metric in the Uk and in Ireland?
If a bottle is labelled as being produced in the Irish Free State that would put it between 1922 and 1937.
When did the Cork brands add the e to whisky?
When did Jameson add "Pot Still?"
When did Jameson remove "Pot Still?"
When did closures change from driven cork to cork stopper, so spring cap, to small screw cap, to large screw cap...
Please add anything that seems useful!
