Thanks for the compliments, Dre! You guys are gonna start making me think I'm a decent modeler. :-) :-)
Unfortunately, I don't know the story behind the Bison decals (haven't taken the time to do any in-depth online research). From the photos I did find, though, it seems like this bird was retired and then maybe restored for display or touring or something....? There is an early photo of it under wraps and looking badly weathered, then a later photo where it's all shiny and new. Who knows? Never can tell with the Russians. :-)
You can imagine applying those decals was definitely a Cold Sweat Moment. Yikes. I went overboard on the decal solution to make sure they didn't rip.
And all the decals came with the kit. The Eduard limited editions are expensive, but you get a lot of options for markings and profiles. I think the Su-25 limited edition came with six. If you're bored, you check out the instructions here:

In any event, reviews indicate that the OEZ/Kopro kit (on which this Eduard rerelease is based), is still the most accurate Su-25 model available (even though it came out in the late Eighties and isn't 100% accurate, either). I don't know anything about the accuracy of your Trumpy, but I think the Monogram Frogfoot was based on an early prototype, not production aircraft.
Cheers,
