In the last cannon post, I closed with mention of similar 3-inch rifle patterns used by both Memphis gunmaker Quinby & Robinson and the Vicksburg firm of A.B. Reading & Brother. You saw this photo in the earlier post:
Compare to this 3-inch rifle on display at Five Forks:
The two rifles share a common external form. Although records are silent, the most likely explanation is Confederate officials distributed documentation for the patterns. But there is also a formal connection between the two companies, with a sub-contracting twist.
Quinby & Robinson and A.B. Reading were among several companies in the Mississippi Valley which answered the Confederate calls for ordnance early in the war. Even without any formal experience in the field, both firms made credible progress. But of course, like many other Confederate gunmakers, the efforts suffered with the lack of raw materials. And like other Western Theater companies, the two firms were endangered by Federal advances.
Quinby & Robinson suffered one additional setback. On September 30, 1861 a fire destroyed much of the Memphis firm’s facilities. The timing of the fire was unfortunate. Prior to the fire, Quinby & Robinson was able to deliver up several cannon a week. After the calamity, the firm had several unfinished castings on hand without the means to complete. So the Memphians turned to other vendors. A receipt from February 20, 1862 indicates Quinby & Robinson turned to at least three different firms. Two of which were in Vicksburg.
Listed on the receipt, A.B. Reading & Brother completed four 12-pdr howitzers and one 6-pdr gun for Quinby & Robinson.
A line below, A.M. Paxton, another Vicksburg firm, received credit for finishing three more 6-pdrs. There was more work for Paxton, but I’ll save that as a tangent to follow on a follow up post. The only 3-inch rifles listed on the receipt were two completed by the Memphis entrepreneur George Washington Grader.
Still, if Quinby & Robinson sent unfinished castings to Vicksburg, is it also plausible for them to send detailed plans and casting models? If so, that might account for the nearly identical guns provided by Quinby & Robinson and A.B. Reading & Brother.
Nearly identical, I say. There are some differences between the rifles from the two companies. To see those differences, one has to look down the bores.
