Chainsaw Repair

I just finished refurbishing a Poulan Deluxe Super 25...runs great....what a great little saw. I do have a couple of questions for the members.

1. The serial number is 11012067. Can anyone tell me what year it was produced? I understand that this model, S25D, was introduced in 1974, but I cannot decode the serial number in terms of year of production.

2. Were all S25D models manual oiler only, or were some manual and automatic?

Thanks in advance for your help.
