Hmmm for me it's a bit of a toss up between:-
BSA Supersport Five
Brno Model 2 (I prefer the tangent sight over the model 1's stand and leaf)
Mannlicher Zepher
I have two of the three
there are others that come close as Walther made a fine .22 sporter as did Mauser. I must admit I did like a Remington that a fellow club member had but cannot tell you the model number. I was not so struck by the Rem 513 that our club secretary had. Not have the chance to try the winchester .22 L/R's.
