Rival to the BSA Standard? What about the Haenel VIE. At first glance you could be forgiven for thinking the Haenel was actually a BSA, until you look closer and notice the name. There don't seem to be many VIE models around but it is a good sturdy rifle.
My notes say, key info: 'Haenel, Suhl, Germany produced the Model VI E (6E) in the 1930`s pre WW2. These .22 calibre, underlever, Air rifles were designed from a B.S.A pattern. It has a 19 1/2 rifled barrel with a crisp clean bore and measures 46” overall. It has adjustable rear sight and blade foresight.
