This is the RIGHT cartridge guide Winchester model 94 Pre 64 Middle production from ~1950-1964 PRODUCTION30-30 cal (serial number ~1700000 - 2700000). This part keeps the cartridge in the correct position as it enters the chamber and does not have the distal end cut at an angle and steel is not as robust as earlier 94 carriers. The screw that goes through the hole in the cartridge guide and holds it in place by threading into the side of the receiver is part number wp71h. These are ORIGINAL parts so the finish varies. The overall length is 2 5/8 inches long.
