Speaking of Priwerisms, do I have this roughly correct for SCSW4?

"Collector opinions have varied as to what exactly constitutes the difference between a Model 1902 and Model 1905 in both .38 and .32-20 calibers. Previous editions of this book have defined the essential change as the addition of the 5th frame screw in front of the triggerguard to the Model 1905. However, a strong case based on factory catalogs and literature can be made that the defining characteristic of the Model 1905 is the change from round butt to square butt, which occurred during the production of 4 screw frames in 1904 prior to the addition of the 5th screw."

Thanks! - Jim
