And to you my friend BP.
It is a .45-70 and the DOB is 1882. There is so much we don't know about these guns. Springfield did a lousy job of documenting their actions. Well take my serial number on my carbine. It is 1809xx and has a star (*) at the end of the number.
Now there are not that many of these considering the number of guns that were produced. But no one knows what these stars mean!!! This is one of the fun parts of these guns, the research.
