120mm howitzer casing question

[wingsofwrath]

EDIT: I just realised I should have posted this in the "cartridge" section, but I don't seem to find a way to either move or delete this thread myself, so I guess it must live here until a mod either moves or deletes it.

So I have two puzzlers on my hand, both having to do with Romanian 120mm metallic cartridge howitzers, so I thought of combining them into a single thread rather than posting two of them.

The first one is the Gruson 120mm L/13 Howitzer Md.1888, originally a fortifications piece, and adapted in 1916 for field use.




This one uses a necked down metallic cartridge with double rim of unknown dimensions. We have pictures from the Bucharest Military Museum of the ammunition this piece used and, knowing the dimensions of the shell, I was able to estimate them from the photos to around these:



The second piece that concerns us it the Krupp 120mm L/11.6 Howitzer Md.1901.



Again, we have images of the metallic cartridges and from that we can estimate the dimensions and they seem to fit with the Krupp 128x84mmR140 which I know has been used by other countries, including the Netherlands and the Ottoman Empire.





Now, my question is - do any of you have any information, especially drawings, about any of these cartridge casings? Thank you!

Here 2 different Krupp drawings for the Dutch 128x84R140. The difference is only the primer thread (20 vs 18 TPI).

Yes, thank you very much!

That's exactly what I needed and that drawing fits very well with the one from the manual that I have - unfortunately I only have photographs because the last time I had this in my hand I was already copying a whole lot so I decided to leave it for another time, but right now it's inaccessible, because the Bucharest Army Museum library is being audited so it's closed to the public.

So we can call one problem solved.
Now let's hope someone else has something about the Gruson howitzer, although I'm a bit pessimistic, because I don't think anybody else adopted it besides us...

Maybe it will come in handy...

I have this in archive, I never identified.
unfortunely no dimension but look very similar to 12cm M88 L13
