You guys are talking like 21st century collectors.

If, 70 yrs ago (or even 100 yrs ago in WW1) imagine I am in the theatre of operations and came upon a holster, they are in a rush and they cut off the belt (the less you have to touch a body, the better), then you realize that the holster rides different on your belt or its too tight in the US GI belt. And they cut some slits in it.
We don't like it, but its the facts and either deal with it or leave it as is
