If I may put forward a suggestion of my own, here's something I've been wanting to see for quite awhile, and was actually getting ready to make myself because I was sick & tired of waiting for someone else to make it.
Any non-scoped bolt-action rifle, such as maybe...
The German Mauser Gehwerer 98

The British Lee-Enfield SMLE (10 shots to the Mauser's 5)

The Japanese Type 38 "Arisaka" (Considered by expert to be the best bolt-action rifle ever made)

Or, of course, the American Springfield M1903

Any one of these would be great, or even maybe just some generic rifle would be fine... just so long as it doesn't come out looking like crap, ya know? ;P
