Looks like a flattened Kong hanger with 3/8" Rawlbolt, Leeper hanger with 1/4" buttonhead and a Metolius hanger with a 3/8" Fixe wedge bolt. Why is the Kong hanger smashed flat?

In these parts of the county, sometime ago, there was quite an anti-Kong movement, with many of those same folks moving towards the then new-wave Bong movement. I'll have to double check my records though....
