If I had to guess at the answer, I would say that the assembly number may have been a "batch" number... so many were produced in a batch and then placed at the assembly tables...
If a problem with a certain batch of parts were discovered by the assemblers that the batch was out of specifications, they would pull the whole batch and have them reworked or discarded.
I did much the same when I was managing a manufacturing operation years ago...
