Last week I was walking home from the library (okay, the comic book shop) and noticed a store just threw out a cash register. I looked at it and thought about the armor stud threads.
At the time I didn't think it was a good idea to walk down main street with a store register under my arm, so I waited for the darkness of night. When it got dark I went out for a walk (with a screw driver) and pluck the keys from that sucker. Good thing I did. The next day it was gone.
They're not close to the screen versions, but they'll do for a scratch build costume. I figure I can at least sand the top of the keys flat.
Anyway here is a sample shot of a few key. (Rough Measurements: bottom 3/4" square, top 5/8" square and 1/2" high)
Now I just need to know... should they be white or silver?
