@Nighthunter, Hood
I know that Psilander did HP O/400 and Bristol Fighter, but He did it in his own, unimitable (and so divergent from SB/FD-standards) style, and I would have to essentially totally remade them, so I just did it on my own from scratch.
As for the SE.5 - when I was drawing it, I had a persistent feeling, that I already saw it on SB/FD, but after checking FD threads I couldn't find it, therefore I assumed, that I was either wrong, or that it was posted on an attachment that was later purged. I forgot that Redhorse did some FD-scale planes in His AU thread and that SE.5 was among them.
@KimWerner
Yes, WhyMe already PMed me about that.
Besides, I took that badge frame from a post made by You, so I assumed (erroneously, as it seems), that it was done by You (as most other work in that field).
I will correct it sometime later (When I'll be in the mood to do so
).
