That would be the M-1903 Springfield, cal. .30 (".30-'06"), a legendary weapon if there ever was one.Sorry; never heard of the song - but add my name to the Irish Sgt.s as one who would be interested if it ever does turn up.
We do have a copy of "The Corporal's Musket" written by a Maine Civil War Officer about the musket his Grandfather carried in the Rev. War. I seem to recall doing a "Lyr Add" here a couple of years ago for it - an interesting song to be sure, and one we don't hear all that often any more.
There have been times I've contemplated doing an album of gun - related songs / ballads; somehow I don't think it would be much of a hit with the "Folkie" crowd (PC thing don't ye see) and I don't do "C&W" worth a diddle. Every time I try to whine melodicly out my nose, boogers pop out and it's kinda gross...
