what is it made out of?
That would be a rule though a lot of people wrongly call it a scale.

no neat sig line
Not so fast there lad. Did you see the opposite side?
General’s rules are precision-made with etched fine black graduations for easy reading and long life.
ADDITIONAL DETAILS
· Flex ruler, 6 inches long, with a satin chrome finish
· Inch graduations by 8th and 16th are on one side, 32nd and 64th on the other
· Rule is ¾” wide
A gunpowder grain, probably for a naval cannon.
I recall reading somewhere that you used to be able to get long extrusions of this, then bend them into a cane, but the internet is failing me now.

Powder Grain - An individual unit of propellant. Commonly used in the form of strips by France, cords (strings) by Britain and Japan, hollow tubes (single perforation) by Germany and Italy, and in multi-perforated cylinders by the USA, as shown at right. A propellant grain with a decreasing burning surface will tend to generate less propellant gas as it burns while a propellant grain with an increasing burning surface will tend to generate more propellant gas as it burns. Propellant grains whose total burning surface area decreases as they burn are known as degressive or regressive grains. Propellant grains formed in balls, cords, pellets and thin sheets burn degressively. Degressive grains are best used in weapons having a short barrel length as there is less need to maintain a steady pressure as the round travels up the barrel. A neutral burning grain is one whose total burning surface remains approximately constant as it burns. Single perforated grains and star perforations are examples of neutral burning grains. Technically, grains formed in sheets or strips burn degressively, but the change in burning surface is so small that these may be considered to be effectively neutral burning. A progressive grain is one whose total burning surface increases as it burns. Grains with multiple perforations and those in rosette shapes burn progressively. A progressively burning grain has an advantage in a longer-caliber gun as more gas is generated to fill the increasing volume as the projectile travels down the barrel.

That's exactly what it is. Can we still tell elroy where to go j/k

Are you smarter than Elroy?
I can speak in the first person, so I may be.

Vicegrip,Damn you guys beat me to it. I used to bring up bags of the stuff from a wreck of the east coast. The cordite will burn when it drys out. It was stored on board in 6 or 7 inch around and 3 feet long metal canisters that were made from steel with brass ends and a brass lid. The steel rusted out leaving the cordite in about the same shape it was in when contained. The cordite was in silk like bags in the steel/brass tubes. One area of the wreck looked like like it was covered in cig butts.
The brass ends clean up well and make great picture frames. I still have a couple 5 gal buckets full of uncleaned ones.
The wreck is the USS Schurz it was a WW1 german gunboat that we took over re fitted with our cal guns and renamed (long story) Good looking well built boat with lots of cool stuff to find. After 80 years underwater it was reduced to a long rubble pile with a bit of hull here and there. I found the tool and parts storage area and spent many a dive digging up spare parts like big split seals, 6 inch ID bronze bearings and brass gasket punches and the like.
Excellent!!That's exactly what it is.
This example was manufactured at the Indiana Army Ammunition Plant during WWII.
Here's a little hint:
It was manufactured under government supervision![]()
