That looks like home, Jim.
Woodies can come in through the trees, and light, hotter than any other duck I know of. Mallards landing over decoys compared to woodies landing in a beaver pond is like comparing a 'copter landing on a helipad to a fighter jet landing on a carrier flight deck.
A few years ago Bill McGuire, who is a national champion sporting clays shooter, came down for a woodie hunt in some beaver ponds. He shot and shot that morning, and never cut a feather! He said "They do come in quick, don't they?".
If your gun is a regular use hunting gun just touch it up and don't worry about it. Your boys will know well where the wear came from, and appreciate it.
