You guys are incredible!
Thanks for the pics of ashtabula, mebbe in my world the B&O will share the harbor here with PRR instead of NYC. Really inspired me to get an ironboat ive been working on finished.
Skip, the decals im looking for are the 13 states herald, primarily for the OS 4 bay W2s and the RS and OS twins, the W7 3 bays are a bit newish for my layout (they started to come on the B&O in 1947, i picked 1948, so some will be present, but nowhere near the numbers of the other types) my equipment register shows 1000 W7 in 1948, no W7A or B yet (compared to about 30k twins and 7k 4 bays).
I can use a number jumble for individual car numbers. The cars i have are a small army of MT OS and RS twins, the RS ones need a smaller herald than the OS, but I can just backdate those and have them with just reporting marks and roadname, no herald. The pic below shows a W2 with the markings i was after;

Thanks so much all, really helped me out; oyeah, I got the issue of RMC i bought, it has an outstanding diagram of an EL3A, complete with DIMENSIONS!
Excited now, Tim
PS. Im now looking for the October 74 Issue of RMC, seems that article is about the EL-5, so if its anywherenear as good as this one, will be worth owning.
