But I repeat, there is nothing similar in Patent to Mongose-X or any Tomba designs.
I was started to think about vacuum solution in 2008., in time of Mamba, and this was the first attempt in Jan 30. 2009. ready to be tested in summer that year:
I used slightly different knot than on the picture above:and a constrictor knot:

It seems to me that STC - Mongoose-X is really a copy of Tomba7N3 but with metal elements in reverse order, and made in titanium instead in stainless steel.
One huge difference between actual TombaX (Tomba700X,...) and Mongoose-X is that TombaX has tiltable muzzle insert that makes loading of the shaft fluent even when bowing the shaft. That insert also makes possible to have very tight gaps between the shaft and the slider and also to have OR of very small cross section on the shaft, like 1 - 1,5 mm not losing the vacuum.
