I just purchased my first Parker Trojan at Cabelas today.

It is a 16bore on a #1 frame-Dbl Triggers, a 1929 gun. She's tired but sound. BBls are sound and ring true. She does have a poorly done brass pin in the head of the stock about 1/4"behind and down from the top and rear of the reciever. When I trip the front trigger, I hear a ringing and feel vibration in that crappy brass Pin. Do you think it's the top of the hammer hitting the pin? No worries on the back trigger and no vibration in the pin either.I tried two sets of snap caps thinking it might be one or both of them , but it does it only on the front trigger. I will be restoring the metal first and then re-wooding, so it is relatively moot but I am still curious anyway. What do y'all think?
