I bought this WW2 era English Bomb Sight. It looks to be made of several different metals (brass, bronze, steel), is quite heavy, and the optics are in great shape.  It’s a beautifully made object.

WW2 Bomb Sight

I am planning on keeping the object as-is, as the object is an antique, and any transformation would diminish it.  However, I’m going to make a decorative mount for it by wrapping a metal doll chain around it that looks like this (note the negative space):

I’ve made a paper prototype by cutting the image on a laser cutter and wrapping it around. It looks quite good, with the bombs not being immediately visible.  I will use a CNC Plasma cutter to cut it out of 16 gauge steel which I’ll then put on the metal roller to make it into a ring.  I’ll then TIG weld the ends together, and then weld the ring to a support that will mount the piece vertically with a slight angle pointing down about ten degrees from vertical so that a viewer can comfortably look through the eyepiece without banging his head against the wall.  I will probably powder coat the result to protect it – not sure if I’ll use clear or black. The support needs to hold a magnifying glass below the bombsight to focus the image properly, as the focal length of the bombsight is way too long.  Below that, I’ll have the “image” itself which will be barely off the wall. The image will say “This is how your great-grandparents’ house was last seen.”
