Does anyone know the AFOV for the Meade WA 18mm eyepiece?

Depends which model you're referring to as they differ:

Meade Series 4000 Super Wide Angle (SWA) 18mm: 67° AFOV

Meade Series 5000 Ultra Wide Angle (UWA) 18mm: 82°

Meade Series 5000 HD-60 18mm: 60°

I think it's before those because it only states Meade WA 18mm Multi-coated.

It's likely the 4000 series with a 67 AFOV. I have the 16mm Meade WA --original series--and it's the same AFOV but manufacturers frequently overstate the fields of view anyway. You're likely looking at 65 to a maximum 68 AFOV with the 18mm original series considering its 19.7mm field stop.
