Hi, /k/

I'm currently developing a first person shooter (not going to panegyric too much about it since that'd be shilling), but I have no interest in using the 1911+glawk+ar+mossberg boilerplate most devs rely on. Recommend me some weird and cool guns you'd like to see get more love.

Not required, but bonus points, if they fit in any of these categories:
> 3D printed
> Hand-made (in the khyber pass way or the PoopMadness way, your pick)
> Chimera'd or workshopped in any severe way
> WWI era or earlier
> Never went into serial production
> You own one and don't care if I use your photograph as a base for the texture

And additional bonus points if they fit any of the following roles I'm trying to fill:
> Bolt action rifle, ideally straight-pull but IDRC
> Full-sized carbine in .22
> Single stack pistol
> Single-shot rifle, preferably in a rimmed cartridge
> Wood-furnished midcentury battle rifle
> Machine gun that is not mag-fed

To help the thread get started, I'll dump a few of the guns I've already modeled.
