The little hammer double of the early years of the Twentieth Century was a nice little gun, certainly a cut above the output of the Crescent Fire Arms Co. factory, but doesn't compare with Harrington & Richardson's A & D hammerless guns of the early 1880s.

By 1912 it was also being offered in 20-gauge.
I was hoping someone would come along that knew, but I finally broke down and searched. Don's article is in Volume Eighteen, Issue 2. According to Don, the November 1882 issue of
Field & Stream carried an S,D&G ad showing the Harrington & Richardson Anson & Deeley style gun in four grades No. 1 $100 to No. 4 $350. The next years Edw. K Tryon Jr. & Co. catalogue listed them in descending order as the A. B, C and D grades. Don pictures a B- and an A-Grade in his article.
The
Gun Digest repro of the 1884 E.C. Meacham Arms Co. catalogue pictures a nice Harrington & Richardson hammerless but only lists the No. 1 with Laminated steel barrels for $100 in 12-gauge and $110 in 10-gauge; and the No. 2 with fine Damascus barrels for $150 in 12-gauge and $160 in 10-gauge.
