Pick both up last weekend Sheridan Blue Streak with Williams peep sight & Benjamin 397-PA in .177. The Sheridan is a hard hitting tack driver and the 397-PA is super fast.
I still have my Silver Streak, bought new, directly from the factory in the early 70's. My dad had some sort of professional relationship with an exec at Sheridan and got the gun at cost. As a kid, I thought the Sheridan was the best thing ever. I still like it a lot.
