Bad gun. Stay away. Where is the gun being sold?

Just kidding. We know a good bit about the Sears Aubrey / Meriden guns.
http://damascus-barrels.com/Aubrey.htmlThey are sidelock's with an automatic safety and chamber indicator. They run a gamut from very plain to some very nice guns. They could also be custom ordered.
This is perhaps the earliest gun made and belongs to Daryl H.

Here is a Model 55 with Chain Damascus.

This is my M97 hammer gun, which I got from John Mann.

Another M55 which I own. This one has Krupp barrels.

This is the entry level Model 18.

The number of models changed over the years. It varied from 18 to 6. This does not include the special guns like the Diamond grade or the $250 gun. Nor does it include the custom guns that could be ordered.
Barrels were available from crystal steel, twist, damascus, Krupp all the way to Whitworth, though I have never seen a gun with Whitworth barrels that I could confirm.
They were made in 12ga, 16ga and 20ga. Most have extractors, though ejectors were available from the beginning. Nearly all are choked Full & Full. A customer could request Cylinder bore.
If you have any questions, please ask. Also, if you could obtain the serial number of the gun in question, also the length and composition of the barrels, I would like to add it to the list.
They were also sold under the name Berkshire. While Sears offered the Berkshire gun, I believe that name was used mainly by the Biffar stores.
