Hands Up!
Mecha’s body is wooden. Sleeves are an old cable and socket. I search a lot for those sockets origin but couldn’t find anything.
Shoulders are from motor shaft. Eye is a part of the 1970 model Olivetti Typewriter. Mecha has a old tube lamp on it’s head which I found on a U.S. Army Radar Receiver Panel. You can see the Radar Receiver Panel here.
