Base of artillery shell or farm junk

[Tigerdude]

Found a parrot fuse about 150 feet away. Is this a base to a shell or farm junk?

Sorry to have to tell you, it definitely is not the base of an exploded civil war era artillery shell. None of those have your object's OFF-CENTER flat-bottomed hole on a flat bottom.

Hey, I appreciate the knowledge . Thanks for the input.

I just now thought of a civil war artillery projectile possibility... the base of a "Flat-Base Hotchkiss," which was an early-war artillery shell used by the yankees, found only at battles along the lower Mississippi River, in that state and Louisiana. That "Flat-base" version of Hotchkiss shell is so extraordinarily rare (fewer than ten have ever been excavated) that I didn't immediately think of it as a possibility. Can you do Electrolysis on it, to remove the rust-encrustation, and give me a super-accurate measurement of its diameter, in hundredths-of-an-inch? You'll need a Digital Caliper for that kind of measuring. (Please measure the diameter in several directions across the flat bottom of the object.)

What put me onto the possibility was (1) your Southern Louisiana location, (2) the presence of a yankee Parrott shell's fuze nearby, and (3) the hole in the flat base appears to be filled with lead. Sometimes when a civil war (or earlier) artillery projectile came out of the ironcasting mold with a casting-flaw hole on its surface, the hole would be patched with lead.

If it is the "base-cup" part of a Flat-Base Hotchkiss, the sidewalls of the cup have been blown/broken off... which is another reason I didn't immediately think of it as an artillery shell's base. There seems to be a broken-off circular rim on the opposite side from where the hole is.

I must add, the possibility that it is the base of an extraordinarily rare Flat-Base Hotchkiss shell is kind of a stretch... but it's worth investigating. Precise measurement of the object's diameter will tell us whether it matches up with the diameter of a Flat-Base Hotchkiss shell, or not.

Fired up! Will put in tank right now. I'll get back with pics and measurements in a few days.

 

[Tigerdude]

Ok. Pics with actual measurements. I've included an interior measurement. just reviewed-sorry about the alignment of photos

I'm genuinely sorry to have to say, based on its very-precise measurement, your iron fragment is apparently not from a Hotchkiss Flat-Base projectile. Your measurements show its diameter ranges from 3.318 to 3.491-inches. That is too large to be from a 3.4-inch caliber Hotchkiss (actual diameter 3.31-inches), and too small to be from a 3.67-inch caliber Hotchkiss (actual diameter 3.58-inches). I was sincerely hoping for you that your find was part of a civil war artillery projectile. But the very precise caliper-made measurements eliminate that identification. Oh well... keep on detecting. The civil war Parrott shell's zinc fuzeplug is a definite sign that you're in the right area for more Artillery finds.

Hey, I really appreciate your efforts and knowledge. Still can't figure out the lead in the cavity, though Someone said maybe a scale weight. Who knows. Thanks again.
