Information is useful. Much better it is available than keeping it 'secret' based on some fear of what someone might do with it.
I have a W&C Scott Premier hammergun chambered in 2 7/8" 10 ga. It is a two barrel set, original damascus barrels and a second barrel set in fluid steel made by HA Lindner.
I was able to research previous owners and even contact people who had known a long term prior owner in Kentucky. (Where I found it.) Reported that he used the shotgun for years with 3 1/2" mags (Yikes) in the unaltered original chambers. (I checked, the Mags will chamber and the gun will close.) Not known which barrel set he used....
I am NOT about to try this.... Yet the information is useful in a general way to understand how tough these old guns can be.
Did you ever get that basket case fixed up ?
I'm sure everyone here would love to see some updated pics.
