AB23 Butterfly Bomb container

Member
As a new member of this board I thought I’d start by sharing some pictures of a container I’ve recently acquired.
This AB 23 container, was pretty corroded, distorted and dented. It was also missing the interior partitions that had rusted off and disappeared long ago.
Someone had previously attempted to bang out large dents with a small hammer, resulting in lots of small dents.

It was quickly apparent that this was never going to be suitable as a ‘concours’ restoration, but I have had a go at ‘tarting it up’ to a state where it is good enough to display.
First, I gave it a bath of Evaporust and then a coating of thick red oxide inside and out.
Spent some time in the garage sorting some of the dents and deep pits.
I have read that these containers were originally dark green on the exterior and the remnants of original green paint was still clinging on between rust pits on one of the fins.

I masked this off before painting the rest, trying different shades of dark green.
Don’t know if that original paint had faded over time, but the best match seemed to be a far lighter shade of green than I’d anticipated and seemed more like ‘Feld Grau’.
I don’t normally like to re-paint wartime relics, but in this case there was only a tiny amount of original paint, which I have left in place with some clear matt lacquer hopefully keeping any further rust at bay.
The focus of my interest is wartime bomb disposal, and I occasionally exhibit related items to the public at 1940s events. I have therefore, rather conveniently, gone for a patina’d look, as if this had been found on an abandoned airfield at the end of the war during the clear up. (That way I could still get away with leaving some of the dings and pits in the casing.) I have even used some model railway, Humbrol ‘rust wash’ paint. Quite pleased with the end result -

It might seem strange to restore something to a slightly distressed state, taking rust off then painting it back on, but the metal gets a covering of protective paint that should help prevent the thing from deteriorating, which it would certainly have done had it been left as it was. Guess I could have just covered the bare casing in Waxoyl, but that just leaves a rusty looking sticky mess that gets on everything it touches.
As the back would not normally be on seen when displayed, I spent less time trying to lose the dings, and hence a bit more of the faux rust finish.

The container came with an impact fuze, which is obviously wrong, so I have put a No9 fuze in, which I know is also wrong, but it will do until I track down the correct 79 fuze.
Also looking for a lifting lug if anyone has any leads on these.
Made up some stencils with best matching fonts to original script as I could find.

I know AB stands for Abwurf Behaelter, (throw down container), and SD stands for Sprengbombe Dickwandig, (Explosive bomb thick-walled), 2 being Butterfly bombs, but I don’t know what all the white stencilling means. (I took details of these stencils off the net, as few original photos show the full markings).
I’m guessing they may have something to do with the altitude required to drop it in order for it to open and scatter properly?
If anyone can enlighten me as to what the white writing actually means, I’d appreciate it!

In my collection I already have ‘half’ of a German bomb container, - not dark green, but apparently originally painted in a buff(?) colour.

This new acquisition however, for all its issues, I think is much better for use in any future public exhibitions I may put on, alongside some of my other SD2 relics.

Hi Chris, welcome to BOCN. You've done a great restoration job on the container.
A few of us on the forum are interested in SD2 and M83. This link has a load of information about them.

The question of German WW2 bomb colors is rather complicated and obscured.
But generally the field gray color of your bomb seems to be the feldgrau indeed, 3 RAL 840 B2 aka RAL 6006 according to RAL 840 R - color used for e.g. SD or NC bombs. But wartime RAL 6006 is a different color than the present RAL 6006.
From August 1, 1942 color of all bombs (except green SBe) was changed to grey beige RAL 7027 (which is, say, pale brown), but as late war bombs are rather bright sand color, this grey beige was apparently changed again at a later date, most likely to RAL 7028 .

I’m guessing they may have something to do with the altitude required to drop it in order for it to open and scatter properly?
If anyone can enlighten me as to what the white writing actually means, I’d appreciate it!
The white writings refer to fuse settings.
o.V. fuer 1000 bis 1900 m = [set fuse] without delay for 1000 to 1900 m [drop altitude] (o.V. - ohne Verzoegerung, without delay)
m.V. fuer 1900 bis 2500 m = [set fuse] with delay for 1900 to 2500 m [drop altitude] (m.V. - mit Verzoegerung - with delay)
Fuse setting was accomplished with a so called ZSK, Zuenderschaltkasten - fuse switching box, charging appropriate circuit of the fuse - with or without delay - at the moment of release.
But I have to confess, the markings look rather strange for me, as both the (79) A and (79) B denote the fuse type installed in the container - so it was A or B eventually? Some bigger containers did have two fuses installed indeed, for example (69) E and (89) B or two (69) D-1, set for different working times, what allowed switching opening time, by choosing an appropriate fuse - but I think, it was not used in the AB 70.
I'm also not too sure if the container type marking is correct. In a textbook case it should comprise of a container type (e.g. AB 70-5) and a number and type of submuniotions below it (e.g. 23 SD 2), divided with a line. There should also be the actual weight of the loaded container just above the suspension point, e.g. Gew. 60 kg.

By the way - the longitudinal red stripes in RAL 3000 (aka 7 RAL 840 B2) between fins denote a container filled with HE submunitions. The red ring at the rear of the body denotes a container filled with incendiary submunitions.
These markings were patterned after regular bombs to some degree, where four red stripes between fins marked SD class (fragmentation) bombs, while two red rings on the body - incendiaries (Brand C, Flam C etc.).

Great stuff Chris, really impressive restoration.
Funnily enough, I also picked up an AB-23 at the end of August just gone, in a similar 'dropped' condition, apparently found in a Finnish forest. Strangely, it's not as bent as it looks.
Mine, for some reason, has holes in the nose, not sure why - either for unusual target practice, attempts at in-situ demolition or an SD2 going off next to it?
