I've been fascinated with the keys that were used during the Cold War for the dual-key launch system of Soviet ICBMs. They are a beautiful, and disturbing, piece of history. Knowing that finding and ACTUAL one was unlikely, I'm going to settle for a replica. I've been "tinkering" in Tinkercad and build a 3-D model based on photos and measurements I found online. I uploaded to Shapeways and for $12.00 I'll get a plastic replica. A Stainless Steel one was only $40. Might just do that as well. I'll post pics when I get the print.
