Just curious, were pre-64 Winchesters built on true short actions, or did they just block the magazine and use a longer bolt stop?
The pre-64 was only made in a "long" action, as when using shorter calibers, the magazine box had spacers added in either the rear or front, or both to allow feeding. A filler (spacer) block was added to the extractor ring that acted as a bolt stop & was made different lengths to accommodate each caliber other than the standard (30-06 & magnums). The ejector was made longer to compensate for shorter calibers.
