Thanks wmaker! Looks like my fuzes are missing the actual explosive chamber but I guess that is understandable...

I paid 20$ + toll for MG 151/20 M round and casing, delivery took few months because of little trouble with new addres... if you are interested getting one, send me e-mail and I might be able to help!

Here's mine.. unfortunately I don't think the fuze will come off. Jochen, are the walls of the shell really thin?

Here's the picture I posted the link to earlier. It shows exactly how thin the walls are

The picture comes from Tony Williams website at http://www.users.globalnet.co.uk/~autogun/

Mauser, the fuze can be unscrewed so you can see what is inside, usually nothing. It might be bit tight if it has been unopened for 50 years but it definitely should be openable unless it has been welded close which I doubt.

You round too is Minengeschoss with thin walls, it can be recocgnized by the round bottom.

I am also hopefully getting MG 151/20 AP round, MG FF AP round and MG 151 HE round soon

Thanks Jochen.. I was able to unscrew the fuze and lift it off. I guess I didn't try when I first received it because I was affraid of crushing the shell walls (that's why I asked how thin they really were). But no worries, the walls aren't THAT thin.
Cool that you're getting the other shells, I'm satisfied with just one mine shell.

Btw, I was wondering, with all the fuss over how things are modelled here and all, does anyone have access to what I'd call design specs? In other words, what requirements were given to the manufacturer/engineer in order to come up with the design of the MG151 and it's rounds? What tradeoffs were made for what reasons, etc. Not because I want to whine, but b/c I'm curious as an engineer.

Brady, email me your address again plz. I lost my HD a while back, and I'm still recovering.

I have already made net page for photos about rounds I have, hopefully I have time to take the photos today and put them on the net.

I also found a net site that has explanations about codes found in fuzes, primers, cases and rounds. Quite interesting to find out where the rounds have been made

That would be great Jochen! Would love to see the codes on the base interpreted. Looking forward to seeing your collection too.

Jochen, can you give a link to the site that lists the codes on the shells, fuzes etc?

http://www.geocities.com/CapeCanaveral/1325/ordcodes.txt

This is not the list I used (the link is on my home computer) and seems like it is not as complete.

There is a book about these codes and it has over 800 pages! The net versions naturally do not have all that information, only the most interesting ones.

Jochen · « **Reply #25 on:** July 30, 2001, 08:20:00 AM »

Oh, if you are looking info about allied ordnance you will disapoint, those codes at the site were used on german ordnance only.

Thanks Jochen.
I am after the details for 2 shells marked
eey 10d 40 (yellow)
and
eey 6e 40 (yellow with blue band)
The shells were used in a test report, and I am trying to work out the exact details of their fusing. I presume the 40 refers to year of manufacture, and your link tells me eey is place of meanufacture. Do you have any idea what 10d and 6e mean?

Jochen · « **Reply #27 on:** July 30, 2001, 11:33:00 AM »

eey means that the component has been built by Metallwarenfabrik Treuenbrietzen GmbH, Roederhof plant. Was that text in base of case or in actual projectile?

40 quite propably means year as you said.

10d and 6e might be lot numbers but I am not sure, they do not seem like standard codes which do not mix letters and numbers together.

I think only way to know what fusing they used is to inspect the fuze itself, it has similar markings stamped. If you look photo of fuze in top of the page you can see it has some markings saying:

ZZ 1505A | efc | 378 | 44 |

Which reads out somethin like:

Fuze type | manufacturer | lot or other numer | year.
