20 gauge CHE found in a garden shed

[B. Dudley]

By "saving the stock" I think he meant being able to use it as a good duplication pattern.

I would call a straight grip 20g with 30" barrels and no safety somewhat rare on a whole. But not super rare. Those would be relatively common features on a target gun. Which is likely what this gun was originally used for.

Yes, a research letter would be the very first place to start. I do not think that the butt treatment was mentioned on the stock. But I would suspect a factory ordered pad might be the likely.
