C) The top 1800scut steel 16mm button is the same as image 1,2,3 connected to a 36mm (1 3/8:) "sew through", that never had a shank - 7 cut steel rivets - fleur de lis of this silver plated metal (some at right side is not as "silvery"). All rivets on both intact buttons react strongly to magnet, while the larger "sew through" base does not. $69. Wear it or take them apart for your next competition division button card. Motivated to sell all of these at a very special price!
