Beautiful set Tyler and Dewey.
Prototype question: did the streamline cars at some point carry the SR circular herald at one or both ends? I have a strong recollection of seeing prototype photos with the herald on these streamliners, but it's so long ago I could very easily be mistaken.
Yes, you are correct, and I do wish these had the decals. Honestly, I have seen them both with and without.
Tyler:
Microscale makes decals for O gauge Southern engines that include the heralds. I don't know if the the heralds might be too large. They also make HO scale decals for Southern and the heralds on those sheets might be the right size.
