So here is a peek into the past with Eagle Talon's 1/72 Northrop M2F2/3 vac-form kit:

No resin or metal detail parts, but nevertheless it was a high quality kit for its time. The instructions have a good amount of color and marking information as well as a potted history. The actual assembly directions are fairly short, but better than a lot of other vac kits.
It was unusual for a vac-form to include decals, even though the subjects were often esoteric with unique markings that would be impossible to source.

Okay yeah, now using the unforgiving visual acuity of digital photography I can see that the black markings are seriously off register. The decals are still useable, I just need to cut away the mis-registered portions and replace them with stuff from the spares folder.
And here is the kit with its progenitor the M2F1.

I also unearthed the Eagle's Talon kit of the X-24A/B. They have been savaged off their carrier sheets and a little worse for wear. PFJN, I can send you scans of the instruction sheet if you like, as it also contains useful notes and drawings of the colors/markings.
