Looks like an interesting old bottle and the bottle type with
it's airbubble inclusions seem to fit the era but whether or not
you can prove it is a genuine Jameson or not will be hard I
fear.
The label looks hand written which possibly
though not unusual for the time makes it virtually impossible to
substantiate. It also states that it is Jameson Irish Malt
Whiskey which is a bit unusual as I would of assumed that it was
Pot Still whiskey but would only state something along the lines
of Old Irish Whiskey or Dublin Whiskey. or Irish Liqueur Whiskey
but I think that is a later term.
The 2 below
examples have similar bottles also but are very different label
wise.
This bottle that was spotted in auction a few
years ago was purporting to be 1885. But because it could not be
verified it did not sell for huge money though. Can't remember
how much though
This Jameson can and has been verified and is
circa 1910-19
