I'm sorry, but that's like saying you have some canned food that the label is missing, but there is a sticker on the top that has $1.29 on it and there is "GT2340DM4" stamped on the side. Can you tell me what is in the can?

Those numbers are most certainly a heat and/or lot identification, but without the documentation, they don't mean much. You could take a sample and have a chemical composition test run. Depending on the composition, and the product form, you might be able to run down the producer and those numbers may mean something to them, but without knowing the producer, they aren't going mean much.
