    US 152mm combustible case

    Hello all,
    This is my first question I’ve posted on this forum, but from what I’ve gleaned from reading other threads, if anyone can help me they are on this site!
    I have recently purchased a 152mm M411A3 TP-T projectile, and have been furiously searching for pictures of the complete cartridge. I want to reproduce the obviously impossible to own combustible case and “consumable” primer, as the army literature calls it. I have been able to find useful measurements and drawings of the side profile, but have not been able to find a single picture of the cartridge on the internet at all. Does anyone have pictures of one or better yet have a reproduced case they can photograph? I have everything else for display as issued, the metal shipping tube, plastic windscreen protector, styrofoam packing and even the cardboard spacers and desiccate wrap. I need only to make a case and neoprene jacket for it.
    One description I read on oldguns.net said it has a fiberboard texture and was light yellow in color so I was planning on turning one out of MDF to obtain the texture unless someone has a better idea based on seeing one. Any ideas?

    Thank you all for the great knowledge!

    edit: I believe it’s a 1978 based on the lot number, trying to figure out picture posting at the moment

    Any chance of a photo of your TP-T projectile? Production date?

    First & last image below are from TM 9-1300-203 Artillery Ammunition, 1967.

    Thanks,

    Brian

    Okay, I added a picture to the OP, and what I believe is the production date of 1978.

    Thank you for the manual photos Brian. I have many such printed documents, but need to see a color photograph of the cartridge in the field or on display. As of yet I have seen none. Also, this particular round had a case with sides flush with the edge of the projectile, no flare as shown in the XM illustration.

    Thank you, M8owner. That is certainly the closest to actual cartridges I’ve seen yet. I was under the
    impression based on the attached photo that the A3 model has a straight case the same diameter as the projectile. I’m still hopeful to see a live one to get an idea if case color and texture.390D9AAD-0CA1-4FBD-BF6B-981AAF79508A.jpg390D9AAD-0CA1-4FBD-BF6B-981AAF79508A.jpg

    I'm not sure about our allies, but the last Sheridans I heard about were being used by Delta Force, because of their light weight. Maybe they will let you measure a real case.

    Hello all,
    It has been a while since I started this thread asking for pictures of a 152mm combustible case. I was able to find ONE picture of a real case from a US Army EOD PowerPoint presentation about how to demil the cartridge. I shall share that picture, along with pictures of the cartridge I’ve created using the picture and measurements from manuals and documentation.
    I have a verbal description of the case having a buff/yellowish color as it is made of nitrocellulose, and having a fiberboard like texture. That being said, I made it from layers of 1 1/4” medium density fiberboard, turned on the wood lathe. It is a slip-fit to the projectile. The primer was turned on my metal lathe, and the case stencil was made using a laser jet and heat transfer paper. The projectile had a filled demil hole in the windscreen, and I matched the FS 35109 color to the existing paint by adding white until the shade was exactly the same. The results are pleasing to me and I thought I’d share in case someone else needs to see a case photo.

    OK. Now you are making me look bad.

    I am the one that started the thread that M8owner referenced.

    That was 5 years ago - and I still haven't started making it.

    You get yours done in what three weeks?

    I get kind of obsessive... I researched until I found what I was looking for, then worked on it as often as possible.
