hi guys i am new i was looking for some info on a old old 410 i have it is a diamond arms st. louis mo. .410 breach action single shot. now for the history of this gun as told by my father, my grandfather, and my great grandfather. who lived on a farm at the mouth of the james river as it emptys into the missouri, in south dakota. the story goes that this gun was left leaning against a building after some men who had been wintering in a cave on the river.they had been there to trade labor for bacon and eggs. and did so several time until the spring thaw. a short time later the territory marshall came by looking for the men. turns out they were the james gang. whos gun it was never was determand and i see no serial number on it. its a neat story and the caliber of this little gun is great for phesant hunting and is very acurate. and i use it every year. i have searched and found some info and came across this forum and did read what was here but is there anything else you guys can tell me about this plain but well built rifle. is the story from my family with in the makers era?
