Auf & Aof

OK, I know that I'm the "Village Idiot" But what does Auf & Aof stand for? I know it's going to be simple once I see it but I can't figure it out. I'm just a simple minded sap boiler.

Brad,
Don't beat your self up to bad! Lots of stuff I don't know. How are the Allis-Chalmers doing?
Merry Christmas!
Regards,
Chris

Chris,
The Allis-Chalmers are doing great now. I spun an axel on the G a few weeks ago, but she's up and running now. They're like a Timex watch they take a liken and keep on ticken. I see you've got a few as well. I'm hoping to us the G for hauling sap this spring. The WD tears up my trails to much when the frost is leaving.
