z1r has it succinctly nailed. To expand a bit... Generalizations: No pre Model 98 genre mausers are large ring. Few different Model 98 genre mausers are small ring. Some illustrations below. Mauser genre Models; First thru Fourth: 1. Oberndorf 98 2. Husqvarna 46AN 3. Erfurt AZ 98 4. Husqvarna 640
Hope this helps more than confuses! Best & Stay Safe! John
