Firing pin for your 6B http://www.gunpartscorp.com/catalog/...aspx?catid=744
I don't think the 87 and 187 use the same part, the schematics appear to be different (but I may be mistaken, I don't have both in hand)
Hardships are quickly forgotten. Intense heat, bitter cold, rain and snow, fatigue, and luckless hunting fade quickly into memories of great fellowship, thoughts of beautiful country, pleasant camps, and happy campfires.
