Need help identifying this old bottle

[Step Back In Time]

Well if it's a 57 then it would be like you said 1957. I was just going off of what the post said. I'm pretty sure those bottles were made in the 60s So it would make sense that it's 1967 but 1957 would work too.

the 5 and 6 looked so similar back then

Yes, it's hard to even see the numbers sometimes.
