The rifle on auction is the second model of the LGV a with what is known as a UIT stock.
The Spezial came in four stock styles UIT, Junior or mini, Tyrolean and the rarely seen three position stock called the Dreistellungskampf.
Walther had many variations of the spezial, milled dovetail with a larger diameter comp tube, both straight and curved triggers, newer style diopter and dual counter wound springs.
They often are found in many forms as Walther made changes to the Spezial as new developments were added.
