The number and styles of old .22 rifles is amazing. Bolt, pump, lever, semi: single shot, mag and tube fed. Many made by one company with another's name on it. Sears, JC Penny, Wards. Go to any gun show, and there are always a bunch laying around.
A few years ago, I cleaned up an ancient
Stevens Visible Loader Pump rifle for a friend. Had never seen anything like it. Strange mousetrap. See how working the pump grabs one from the mag tube, raises it up, and shoves it down the chamber?


Little information on the Winchester 55.
