More or less, without checking, the Tex 86 is a later version of the Slavia ZVP, but with a plastic grip, adjustable sights and adjustable trigger (That little screwdrivery bit in the back can be used for adjusting the trigger)
I have only had one of these and gave it to a relative. It is something that SHOULD be good but I actually prefer the ZVP, which is a better copy of a Diana Modell 5.
