A lot of Hobby Boss' 1/72 props are geared toward beginner/easy assembly and so they tend to play fast and loose with the details. I've got their 1/72 MiG-3 and it's very light in the way of instructions.
On the other hand, Hobby Boss (and sister brand Trumpeter) does have a tendency to flub on paint callouts. Case in point, I'm building their 1/48 Me 262A-1a/U4 right now, and while many of the parts and details have appropriate callouts, there are a few that are just...totally absent.
Best bet is to find actual pics of actual aircraft and go from there, but if that's not possible, you can usually find a consensus among other builds that pop up on Google Image Search.
