A question about a crack in a stock on CHE

[Francis Marshall]

I recently purchased a 1904 16 gauge CHE. It appears to be, at least to my eyes in original condition. It shows signs of a long life afield. There are very little case colors left. All of its characteristics match the Parker research letter. There is a small crack on the right hand side, near the receiver. The crack appears to originate at the small pin at the bottom of the receiver, closest to the trigger where the stock meets the metal work. The crack is less than 1 inch long. To me it is minor. I’m planning a Montana grouse hunting trip September 1. My question is. Should I leave this gun in the safe and not shoot it? Or have it repaired or the entire stock replaced. All opinions are solicited. Photos hopefully below.
