Auto carriers were imported as individual replacement parts back in the day and would not have been found inside of an assembled (imported) gun. Any full-auto carriers inside an AK were neutered before being sold. It is likely a pre-89 specimen you have. The sprung bolt would have been a Polytech item but they may not have been sold together. Un-numbered auto carriers are out there, I was lucky enough to have found 2 in the last year for a couple of my projects.
You have a receiver with both notches so it is only fitting that your carrier be auto too
