Description
45 caliber M3 SMG, featuring late style rear sight and proper markings. Earlier sight was simple L-shaped piece, rather flimsy one.
Economical and simple design, very efficient when produced by car manufacturer: not only "good enough" but also up to 8 times cheaper than Tommy gun! ($15 per piece during WW2).
Modeled in Blender 2.79b for "Darkest hour" mod for Red Orchestra (guess it is minor spoiler ) 8960 tris including some of internal parts for brass check animation. Real apperture was 2 times smaller, but it would limit FOV too much for SMG in FPS game.
