K4 Bombing Computer

Here is one of my favorite devices: a “K-4” bombing computer. It’s a favorite because:

--It is old (current device has 1954 markings)

--It computes using electric-mechanical analog mechanisms

--It is very complicated, likely impossible to us to reverse engineer

--It is for the military

--It is very unknown!

About the unknown... I can find almost nothing about this device. The closest are two pictures of an earlier device shown in Pictures 12 and 13, as referenced in https://usautoindustryworldwartwo.com/harris-seybold-potter.htm. These pictures show something much more primative than our device, but abviously there is some resemblence. Maybe this is a prototpe and never used, but its high serial number
