SB bomber tail numbers?
 

I was noticing that the 2 latest versions of the SB bomber with the pointed nose engine cowlings dont have tail numbers available. The earlier flat nosed versions do. The skins seem interchangable thru out the series. Using default skins same problem, not tail numbers on the needle nosed versions. is this a bug or historically correct?

bug and it will be fixed sometime

that is interesting question because as base for modification was used default models... i suppose it could be bug..
