Very cool. It has a knob I guess to zero the gun in at 100 feet. Seems you would be SOL if another plane was only 100 feet away shooting at you. Nice addition Martin.
Nice item, would this poster of mine have been related ?
Cool poster, thanks for showing!
Hi, new guy here.
I acquired a K-4 several months ago, cleaned it up, and it looks great.
Problem is how to display it. It was suspended within the ball turret in what would look like an upside-down position compared to other turret sights.
And its very heavy. Any thoughts?
Also, I've been looking for the technical order for operating/maintaining the K-4. Anyone have one or better yet, a pdf version?
