gunsaholic,
Almost always when a pin/peg or screw is found in the wrist of a gun stock it indicates that the head of the stock was at one time cracked.The traditional repair[Other than restocking] was to glue the crack and fit a screw to pull the head together.Some times these screws are set in engraved plates fitted into the stock.This repair can be long lived but in any event the value of a gun with this type of stock repair is less than a gun with a sound stock.
See the Amateur Gunsmith by Desmond Mills and Mike Barnes page 151
Yes, I removed the stock and there was a fine crack internally on the top of the wrist.
