Someone must know about this thing ! I have scratch built one and if I finish it without the weird circle things would that be acceptable for the Railroad campaign?? Must know ready to paint otherwise. Comments please.

Here's a photo of what I mean. What are those round things.

Would you be refferring to the bumpers or the lights above them?

Not the bumpers or the light group, those other circle'y things, one is an out'y and the other an inn'y. I have seen three different versions. One as shown on both ends, one with none at all at either end, and one with them only on one end and not the other. Also the one with blank ends also has no Maxims sticking out of its sides. Which one is accurate, or does it make a difference.

According to the drawings you can find here :

...it seems the hemispherical part is a headlight cover and the circular opening is a machine-gun port.

Hey, that's the site I took the drawings from. I guess then I must add those items to my model. Thank you Frenchy
