That Whatzis, revealed!

Those of you who opined it was a powder can were essentially correct - I was pushing you to see if you would figure out it was a *big* powder can.



Because it is a big powder can, or, as the Navy terms them, "16in Tank, Mark 4."

It's the powder can for the 16inch guns of the battlewagons. Seen here below with some of its kin for scale. A 155mm "Green Bag" can (the skinny one) and a 155mm "White Bag" can (the squat one) along with a 155mm inert round and a 203mm RAP round (made of resin as a training aid).  Most pictures in this post will embiggenate if you click on them.

.  That "bayonet" fitting on the upper rim that had Og so intrigued was part and parcel of being able to lift and secure the cans.  The powder was removed in a room separate from the rest of the turret and the powder bags sent to the guns via "pass-throughs" and hoists - all intended to minimize the ability of fire to flash through the system due to combat damage or accident.  Since the powder is sensitive to moisture (especially the black powder igniter bags) the cans were able to be sealed air tight - and used a wrench to do so - which is where the gear teeth came in - to provide the leverage for the seal.

These cans would hold three charge increments - like this one here, seen sitting in the can.

Unsurprisingly, this thing *dominates* a room.  At least it does at the Castle outside the Armory Door.



Thank you for playing - you guys get better at this all the time as you suss out all my little tricks and traits.

Now excuse me, I have a mission to go complete.

I just didn't feel right contributing after having had the privilege of seeing it in person. But it was quite amusing to watch the fire adjustment on this whatzis!
 
Sweet! Do you have any pictures of the mechanism that attaches to the outside of the can to "Life" or even lift it?
 
Good choice John, intriguing and educational.
 
You do this just to make me feel like a lesser man don't you?  Bully.  I don't have any cool toys like that.
 
Told ya it wasn't from any model of B-52.  Buncha squid pikers don't even have decent size boom-toys to play with!
 
 Reminds me of the toy room at CFSME.

Cheers
 
Sir,

Would that be a 3" 50 training round next to the 5" powder can?
 
Old QM - yes indeedy!  I have the various and sundry wooden versions as well.  We can test the whole ammo system, if you can find a ship that needs it.

JMH - yeah, but that's my basement, not some officious government entity's toy collection. 

Mark - sigh.  You are a one-trick pony, boyo.

'Phibian - Indeed, I do.  I treat all braid-wearing sailors this way.  Besides, you could have cool toys like this if you wanted to. I can hook you up with the right people.  Unless, of course, Salamander 6 won't allow you to...

Colin and Josh, thenkew.

Og - yeah, you've got a spell-check snark, I've got a 16in Tank, Mark 4, w/increment.  I can fix my problem...  Neener neener neener!
 
 So, what was the axel and the gear all about in the pic in the previous post?
 
QM - can you see the links in the post?  Specifically the ones contained in this passage: "and used a wrench to do so - which is where the gear teeth came in - to provide the leverage for the seal."

If you can't see the links, drop me a note and let me know which browser you are using - I'll test it and add it to the list of bugs.  If you just missed them - the text I marked in red in this comment are the links in the post - which answer your question.
