I to find period scopes becoming few and far between. I favour Tasco, especially the AG and FM range and were never a fan of the Kassnar range although I do have a Kassnar Beta3 model somewhere. These classic scopes are still available but you have to be quick or lucky (or both) to find a good, cheap example. Gone are the days of the Tasco 2-7x32AG for £50.
It wouldn't be the first time, or last, that Ive bought a scope then a rifle to fit it.
A good compromise, (and future classic?
) is the Simmons Pro Air series but even the prices of these are on the up.
