I have not heard of that 1933-34 ACL. Personally I have doubts about the authencity of that bottle, but I don't know everything. Where did you find that info?
The debossed bottles with ACL on the neck do exist and I think are a transition bottle right before they started using the regular 10-2-4 red & white ACLs.

The so called 1933/34 bottle belongs to Doyle Baliley who helped write the the Dr Pepper Bottle and Price Guide that came out a few years ago. I wondered about the date myself but at the present I do not question Doyle's expertise.
