Interesting point about mechanics changing on lower grades. Lefevers lost the dolls head on DS and I grades, but still don't wear out. Any others whose mechanics change on the lower grades?
Parkers; They lost the Doll's Head on the Trojan. Not of course mechanical but the Trojan lost a lot of the frame sculpting as well, just not as good looking gun in many folks opinion.
DS & I Lefevers also lost the cocking indicators, though there have also been a few very high grades turn up without those as they didn't fit in well to the engraving pattern.
