Irish Glass Bottle 3” cork top

val

I found this Bottle beach combing in Ireland. When found it had a cork in place which has since deteriorated. The bottom is marked IGB 215 6. It has seams running all the way up each side and a horizontal seam below the lip.

I would like to find out age and what it may have been used for, my guess is that it was a medicine bottle.

Sorry, I should have stated that IGB is the Irish Glass Bottle Company founded in 1878.

It appears the mold seam goes up to the top of the lip and then wraps around the body under the lip. While I am not quite as versed in English/Irish bottles, it does appear to be machine made.
