Paul:  We have been crossing trails without knowing it.  My wife is a long time friend of Joanne's through the Pontiac Zonta Club.  I will try getting your address through a PM.  I will send you a replica blade but it will be too thin (.045").  You can set it in place with some black adhesive or JB Weld and make your own pin by turning down a section of nail.  This will let you play at the Range until you find a better solution.  Chuck McArthur
