Swiss cleaning kit

[Chickenthief]

Well this was a given one for the Swiss as they had the kit from the 1882 revolver.

But you have to give me this: It is a neat piece of kit!
There is a ridge at the bottom so the stell part wont push through under load.

One thing that i havent been able to figure out is: What is the slid in the brass extension for?
There is a fine jag for tow, so?
