I don't think yours was likely to be soda that early. I'm not aware of NDNR sodas being used prior to the 60s or so. It was probably a beer bottle brought up from the States.I've found the small version in clear, dated 1945 and made by Owens-Illinois. Same texture, same everything except for the color. I'd assumed mine was soda, but I'm just guessing.
I was surprised to learn that they were making these No Deposit bottles as early as the 40's.
