Same question with Tunnel Motors.
As built with the full light pack?
As time went on there were tweaks to the lights.... beacons got added, the high headlights and gyralights came off, ditch lights went on.
Speed Letters or Roman?
The tunnel motors have enough evolutionary changes to be their own project.
If UP is an option, then I assume its the final form with the high headlight plated and the gyralight removed, but you need to study the pictures as its a 'no 2 alike' scenario.
I'd love the snoot noses, but I understand the need for standardized cabs and noses. If the lighting causes more nose tooling to be necessary... maybe Late model 123" Snoot nose with just a headlight and the notch from the gyralite + ditch lights (8300 numbers), and as built with 88" nose and the full lights pack?
