Springfield Armory’s first breechloading arms were 56 .69 caliber muskets converted to breechloaders in 1860-1861, but the outbreak of the Civil War halted any further work on the project. An additional 600 conversions were in process at Harpers Ferry, but few if any were completed before the Armory was destroyed.
I am seeking more information on the .69 caliber Morse cartridges, including photos and dimensions.
Note that these are not the same as Morse’s other cartridge for his breechloading carbines made at Greenville, SC, during the war, or the later .45-70 cartridges made at Frankford Arsenal based on his patent.
I understand that the .69 caliber cartridges are sort of a case with a rim, and a bent wire soldered to the inside of the case to act as an anvil for a percussion cap type primer. The remainder of the base of the cartridge is filled with a rubber (or rubber type material) with a hole in the center and is pressed on to hold the cap/primer in place and seal the breech.
Where were the .69 caliber cartridges made, when, and how many, and what happened to them?
Any of these for sale anywhere? Even reproductions?
Thanks in advance for any information.
