These appear to be Canon's internal part numbers.

Thank you for link! This is nice example how to part serial number leed to usefull info.
This was indeed be a copy machine, and I imagine that in uncommon parts is used some other standard, but not know why... only logical explanation is that are not produced for separate sell... confusing others.Comment
