Our contact at Old Parr's parent company archive department tells us the Grand Old Parr bottle design changed very little from the late 1970s until the late 1990s, but the bottles you bought in South America appears to be the 1989 design. The bottles bought in Houston are newer bottles. They have not been able to find an exact match in the archive collection; however the bottle states that it was imported by Diageo which means it was made after 1997 and bottles of a similar design in the archive are from 2002 so it is thought the bottles bought in Houston are around 10 years old.
