I wrote the article in The Double Gun Journal, it was a two-part in two different issues. Observed serial numbers run from around 1000 to a bit over 7000. There were lots of parts and guns in-work sold at the time of the receivership in 1904. In the 1900 Model the A- and B-Grades were essentially the same plain guns, just the A-Grade had twist barrels and the B-Grade Damascus barrels. When the 1902 Model came along the B-Grade got a bit of line engraving and they added the 16-gauges to the offerings, the Trap Gun and the D-Grade. To date only two of the Trap Guns have surfaced, the one I showed in my article and the one pictured in McIntosh's Fox book. They are consecutive serial numbers in the 318x range. I've recorded more D-Grades!! Both of the Trap Guns are restocked, mine better than the other and I have the remains of the original stock.
