Loren,
Harrington & Richardson started production of their single shot smoothbores in 1900. These little guns were so popular that between 1900 and 1905 Harrington & Richardson expanded their factory 3 times. I believe that the 44 Shot was part of the original offering. They continued to offer the 44 Shot until about 1913-1915 when the changes in the tariffs made it economical to start importing the 410 shells.
I posted on this a while back:
http://www.doublegunshop.com/forums/ubbt...df792#Post20229The value of the Harrington & Richardson single shot will vary with condition. So what else is new? In poor condition they usually bring about $100, in 95%+ condition they can bring $400 or more if a die hard Harrington & Richardson collector needs it to fill a gap. Exactly how many were chambered for 44 Shot is difficult to tell. Shortly after WWI a number of companies were accused of profiteering during the war. In a panic many companies destroyed their records. Judging by the numbers I see, Harrington & Richardson seemed to have produced a large number chambered for 44 Shot. There are always a couple around for sale, unlike some of the other makers...
The earliest guns chambered for this round that I have been able to identify to date were sold by Merwin & Hulbert in their 1889 catalog and were most likely made by Hopkins & Allen.
The cartridge itself has been around since at least 1873. There are 4 major variations in the loading. A full box in excellent condition of some of these loads can fetch $300+.
The guns were marketed as boy's guns, ladies guns, taxidermist specials, etc.
The most famous was the Marble Game Getter. In all over 20,000 Game Getters were produced from 1908 to as late as 1961 according to company records. After 1934 up to 1940 it was a special request item. Marble tested every gun before it left the factory. Their tests were all done at a 50ft. range behind the factory. This is also indicative of the fact that the majority of the Game Getters had 12" barrels.
