This is a Bulgarian Lock called the Mauer NW4. Its a dimple lock obviously with 6 pins and 4 sliders, similar to the Mul T Lock MT5+. It also has another security feature and thats the interactive element in the #1 pin position. This is also like the Mul T Lock Interactive+ in that it raises the pin higher than a key can. It has 5 passive pins on the side of the keyway. If you're looking for a challenge grab yourself one and start picking. Its a 3 star SKG lock so its the highest rate.
