OK. I have the First DLGE PS1 F3 A-B-A set. I don't have the units or the box in front of me right now but I have a picture of them.
The unit numbers are #9546A & 9548A
Sorry but I can't make out the B unit #
They have NO Trainphone Antenna or Windshield Wipers
They do have the red [Slave unit] and green [Powered unit] marker light bulbs on the nose above the number boards.
The number board fonts are small just like in the photo.
