C'mon, somebody's got answers...see the red question marks below.
1. Would 93904 be the mileage upon retirement?
2. I know the square with dot means slicktop, what about the "M"
3. Schedule # of 3-245?
4. Another "M" and not sure if that's just a smudge or a mark of some kind.
Also, for those with the in service dates on the red Zymo? label on the dash. Is the date form 03-28-83 or was the zero dropped for 3-28-83 like on the card?
