Help ID'ing Artillery Shell

[CINDERS]

The I.D of the case mouth Brit is 4" so could not be a 105mm but good suggestion, some one will have the answer I am sure.

Hi All,

I felt the need to post back with a definitive answer. I've prolly spent over 10 hrs Googling various artillery stuff, finally found "Robert's Armory" with actual contact info, and they were very quick to reply.

This is my e-mail to Robert's Armory with their reply:

    Hello,

    I found your site while Googling around looking for a possible ID on
 an artillery shell casing I bought last year.  It's been that long and I
 still haven't figured out what this is!

    The throat is 4", the base is rimmed and 5" OD, OA case length is 25
 3/4".  There is a slight swedge below the 2 cannalure grooves.  All
 stampings appear to be in English language characters.  Hi-res pics
 below are from my Imgur gallery and zoom nicely.

    Here is the best pic of the base: https://i.imgur.com/xsm3VdH.jpg

    Any help much appreciated!  I'd like to build a projectile for this
 but don't know where to start w/o an ID.

 	Thanks!

Guess the throat size is not necessarily the projectile size, there's around 5mm difference on this one. Now I can poke around and try to "build a bullet" for it...

Drawing in the OP of the stamp now also makes sense, Kriegsmarine acceptance WaA stamp and inspector number.

Could the C/32 refer to the 105mm German SK C/32 gun? Looks like a similar case.

Hats off to Brit Plumber
Congrats Russ,
Over a year of investigation.... Can't sleep, always trying to figure an angle, can't eat, bug eyed from looking at a pc screen, hair getting grayer.... etc.
Why do we do this to ourselves ?
Oh yea, it's just a Hobby

[RASelkirk]

Yup, Brit Plumber called it! Oddly, there are at least two case lengths for the C/32, this one (657mm) and a shorter version (459mm). Now to find a scale drawing of the projectile so I can "fake" one that's close...

Pile of round fence posts.
If my Father was still alive he'd have something carved/whittled up that would look good by the time I got home from work.
Years back he was visiting and mentioned going out in the canoe while we were at work.
He didn't notice the paddles in the cluttered boat shed.
When I got home he was out there paddling away. Down on the dock I helped tie him off.
He handed me a old true 1" x 8" piece of old barn oak he'd carved in to a paddle.
Had to laugh, but it's hanging on the wall all varnished up. Heavy as heck.

Hi All,

I found a guy on E-Bay that 3D-printed me a shell with fuze, vaguely going by dims off the 'net. He's waiting on me to state what color to paint it and what text to stencil onto it. I have spent at least 20 hours Googling and have not found a single reference to a casing in my "658mm" length (not that it really matters), most are 459mm or shorter including the U-boat deck guns. It must be either a flak round or off a capital ship. Possibly because of this, there is virtually no info out there on the SK C/32 round other than the standard FK (field kanon).

The standard naval HE round is yellow (gawd, I hate yellow) so I'm looking at painting it black (AP?) with copper driving bands. It seems the fuze for all rounds is natural aluminum.

I am about to attempt threading on my pre-war Atlas to make a suedo-primer and complete this project...

What I'm really hoping is someone here has pertinent info on naval 10.5cm shell colors/stencils.







Hope you can help!

naval 10.5cm shell colors/stencils

Russ,
I found some information you may or may not have seen yet.
First I found this example of an Inert WW2 Kriegsmarine 105mm Illumination Round For The 105mm (105x658R) SK C/32 Naval ....... I believe it may be like yours but am really just guessing.
The Site does give a description of different Marine craft uses. On page 12, 3rd from the top, Click on See All Images:

Artillery Ammunition 37 mm +

Here... Wikipedia with some history about it. Besides the Germans it looks as though Romania and possibly Spain used this gun. Norway used it Post WWII for Coastal defense until 2002. I believe I read some where that Nammo loaded Anti ship rounds for Norway until they stopped using it. (Wonder if in Norway if there might be a nice round setting displayed from pre WWII ?)

10.5 cm SK C/32 naval gun - Wikipedia

Here more on specs and loads... etc:

Germany 10.5 cm/45 (4.1") SK C/32 - NavWeaps

Here Codes, Specs, locations and the size-colors of Stencilled lettering, depending on loads.. etc..
When opened - Clicking on the first picture with give you a enlarged booklet you can flip thru:

WW2 Equipment Data: German Projectiles - Introduction and Colour and Markings System

I hope you can find a little help from the above. Even if it's just a little Tid Bit.
I wonder if there might be a German Museum or the like that hay have an example you could see to get a better idea of how they were marked.... Color and size.

Good Luck,

[painter777]

From another forum.

Sorry ........ Yellow !!

105mm sk c32

[RASelkirk]

Thanks Charlie, I'd seen them all except the first one (illum shell). We're gonna go with yellow, it's the only color that seems to be "out there" in the explorable universe. I've seen pix of one that was pretty crusty which looked to be corroded black with copper driving bands, but not enough info to get "close enough" for a repro. Sucks to be yellow, but it is what it is...

Thanks!

Russ
