Jack, nothing, just rubbed off the old dried up oil and blood and started shooting birds. Yes, it is likely the 3rd earliest documented by those who care.... oddballs. It has some interesting scratchings that don't show up. The poor birds get roughed up a bit when put in my shooting pouch along with the water bottles and such. She... is a griffon, and the 'feathers' wear off during the season, that's what the wireyness is for.
