Fallout 3 and NV- figuring out the scale and getting a 3d model of an item

[MLG at DOW]

I would love to know how one could scale an item from either game to 1:1 scale as it seems difficult to figure out how to do this. How do people make 1:1 scale laser rifles, for example?

Another thing I can't figure out is how I would get a 3d model, or every surface of an item so that I could make the scale And the details accurate.

If you are wondering, I really want to have a 1:1 scale Red Glare or shoulder mounted machine gun prop (as insane as that sounds. But if I simply look up pictures of these weapons, I only find pictures of one side that don't show as such detail as the in-game model. Thank you for your time and bye bye!

For the laser rifle probably they compare part of the model with real life similar part (for example barrel or stock, with standard dimension) and resize all the others. In the red glare or machine gun you could use the entire long opf the weapon and compare with a human (1.80); I think red glare is 1.1 m long. Hope it helps.
