20 gauge CHE found in a garden shed

The verdict on these barrels cannot be rendered on this site. Although they seem savable, only a professional double gun barrel man can make that determination.

In my view, there are two good choices in that regard: Kirk Merrington or Brad Bachelder.

Since these tubes are fluid steel, some pits might be weldable. File work should be kept to an absolute minimum in any case.

Rather than elicit more speculation, I suggest you send the gun to a pro. Then heed his advice.

Not a Parker but this is my early LC Smith Syracuse extra heavy Quality 3 10 gauge with 32" barrels that had heavy pitting near the breach. The work was performed by Brad Balchelder who used laser to weld under magnification. Call him and I'm sure he will explain how he did it since I am not sure exactly how he did it. In any case, to do this on Damascus barrels is amazing. I'm sure he can help you with fluid steel barrels too.
