As I was going through my "common" pile, I noticed a slightly different CD 113 Hemingray than I have ever seen before. it is on the right in this photo. I put it to a "regular" one. The one on the right is index [130], while the left is [040]. What I noticed about the right one is it is much heavier with a thick skirt (1/2 inch ) and a much more pronounced and defined upper wire groove rims. Is this anything special or typical of the [130] index. Thanks !!!
