44-60 bottle neck

[Nuclearcricket]

After posting on the Shiloh board and getting nothing but opinions on what I should use and do I figured I would post the same question here and see what I get.
Does anyone on here have any information about this cartridge? What was it used in, used for, what is the history behind it?
For those that don't know what it is, its the 44-77's little brother, its only a 1 7/8" bottle neck case, BACO makes them from the 348 case.
