P&le commuter coach numbers

Does anyone know the road numbers of the coaches that ran on the p&le until 1986? I’m looking into the commuter train. I’ve seen news footage it looks like they were 85 foot stainless steel coaches painted nyc green. I have also seen a photo that shows 6 coaches on the train. I can’t read the numbers. Any help would be appreciated. Thank you.

I have a 1975 copy of Randall's Railway Passenger Car Annual which lists the following cars for P&LE:

400 x-L&N 3200 (60 seats, ACF 1946)
401 x-L&N 3203 (ditto)
402 x-L&N 3103 (ditto)
403 x-L&N 3101 (ditto)
439 66-seat coach
