Owens Illinois ID

[simulant]

I've got this small amber Owens-Illinois bottle but I'm not sure what the code on the top indicates. I'm reading it as "J6 SB" but not 100% on the J. What does that part mean?

Also the date code looks to be an 8, so is this likely a 1938 bottle?

Thanks!!

most likely a mold code.
