I see the market differently.  The vintage guys, the straight military purists are not going to want a "reproduction".  No market there.  I see the market as very high end ($3K-$5k?) custom sporters and maybe a few for guys who want to try Krag-era long-range match shooting. 

Several of the big-time collectors of between-the-wars custom rifles have either passed away or have disposed of their collections.  There are custom Krags and low-numbered 03s that are beautiful.  There has been one serious accident and that was enough to retire the 03s.  There are guys with $$ who are serious enough about classic-style hunting to keep the high-end custom gunsmiths busy.  So a 5-shot or 3-shot Krag action in .30-40 or .35 Winchester or .405 Winchester, with premium wood, a good barrel, and appropriate sights will find a home.
