It has a half-the-barrel length magazine...it IS a falling block, the whole bolt-carrier assembly drops down, picks up next round, then comes up to feed the round. It does have a "22" mark on the bottom rifle where the lever pivots (possibly called the receiver?). And the "mark" almost looks home-made....I haven't seen a LOT of Winchester proofs, but, picture 1 ( sorry it's so small...dang 248k limit!!) can't even discern what letters are supposed to be!?!? I see a T, a -w or m for sure..."p" looks pretty obvious...or a upside down small d? Serial number is crystal clear....tee hee...go figure. After looking at my limited resources, I was leaning towards a Stevens or Marlin...I have more (hopefully larger and clearer)pix coming in now...post them soon....and thanks to y'all, this is a GREAT site to learn schtuff.!
