Eric -
I asked the same thing a couple of months ago and received this from Dave at I-94 Enterprises.
Howdy, Thanks for the inquiry. I address primarily fighters, not bombers in that scale. I can get you to fuselage insignia but not the large wing insignia, which for 17's was 70 and 75".
Largest US star/bar I have on US 114 is 40" at 1/100 scale, so 57" in 1/144. That would be an undersize wing insignia. Fuselage insignia would need to be 40-50" actual, so 28-35" at 1/100 scale. US 114 have insignia at 30,35 and 40" in both 1/100 and 1/144 scale.
If you're looking for basic insignia and lettering, I'd recommend a visit to squadron.com. While there isn't much in 1/144 decals, you should be able to use fighter decals from 1/72 models for bombers, and 1/72 has an enormous variety to choose from.
Sorry I can't be of more help. 1/144 is the orphan child of modeling scales.

I thought the idea of using 1/72 fighter decals would work pretty well and have been doing that. Here's the search for 1/72 decals at Squadron. Take u r pick.
