The cork top would suggest an older bottle but I feel this is still mid 20th century - a hunch. What I cannot see from the photos is the mold seam. I am wondering how visible the seam is on the neck mouth. This would help determine if it is machine-made or not.

I am at a disadvantage since this is an AU bottle and I am here in the US. It does remind me of the Paul Jones whiskey bottles of the mid 20th century - see https://forum.antiquebottles-glass.com/discussion/3995/old-brown-bottle-19th-century-or-20th-century-reproduction
