Civil War Grenade Launcher?

[Dusty Tagalon]

Finally got around to building a replica Ketchum grenade for my shorted & shaved 1863. The core is a 1/2" line float.Still haven't found any providence for it, but I like the look. I the barrel was in better shape, & would actually try it.
No Indian chop, Indians would not have removed material from outside of barrel.
See you at the Grand Muster.
I will bring gun & grenade to muster for discussion, also will bring a flashlight that fits in the bore to show you why I won't try firing it. Plus the weight is off to prove concept. The 1 pound Ketchum, probably weighed about 20 ounces, my model weighs in at 6.5.

That looks like something we all need - now for the test fire...

The 1873 Springfield 45/70 was use as the base for a line throwing ship to ship gun.

I know of one earlier account where in 1836, a muzzleloader was so used, though it was a standard issue 1832 Musket.
In 1836 , the Lighthouse keeper at Cape Florida was shot a line from such a musket in his rescue after the Indian attack.
Lt Lloyd of schooner Pee Dee fired a ramrod tied to a small line up to Thompson (the light keeper), and used it to haul up a rope strong enough to lift two men to the top, who could get the wounded man down.

Perhaps a candidate for and Indian cut down musket.
