Yes, is is a great avatar and diagram Mike! About the diagram; it is not all shoe buckles pictured. The bottom row for instance is sub-rectangular and round stock buckes, sub-rectangular, round, and oval knee buckles, double spiked garter buckles, etc., with the next row up being knee buckles, hat buckles, etc.. The shoe buckles are the ones above. It can get confusing sometimes when you don't have a key to go with the diagram.
