Then tell Elroy "what is it"

Or if you like tell Elroy where to go.

He's not talking about that crappy 6" scale.

stupid guess:
pepper shaker

non-stupid guess:
some sort of restricting orifice? - looks like it's made out of rubber, so I'll stab in the dark at some sort of heater / coolant bypass

That would be a rule though a lot of people wrongly call it a scale.

Not so fast there lad. Did you see the opposite side?

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.

Could well be...
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.

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.

Vicegrip,
Wow, that's an incredible story! How deep down was that wreck? Were/are you allowed to keep the stuff you find in situations like that? When I was young and dreamed of diving for treasures and lost artifacts, I understood marine law to be that anyone who found anything on the ocean floor and brought it up had "salvage rights" to the items, period. But recent discoveries of gold and silver have been challenged by Spain, who claims sovereign rights to the booty, even though it is in international waters...and even though the Spaniards murdered, raped, and destroyed the native Americans they stole it from!

Fascinating.

I'm smart enough to know that this isn't a tool and would have posted it in the free parking area.
