Unknown 12 cm and 15 cm Canet (French, 1889)

[Hoeksel]

While browsing through "Revue d'Artillerie" I found attached image of 3 quick fire rounds, shown on an exposition in 1889, system Canet, for navy and coastal defense. I think the shown 10 cm is the 100x820DR123 shell case which you can often find in France (often marked model of 1891, 1892, 1893, 1897). But I have never seen the 2 bigger brothers of 12 cm and 15 cm. From the text I can take away all three guns are L/48.

Based on the images my estimation is, assuming the 10 cm is indeed a 100x820DR123:

12 cm = 120x902DR

15 cm = 150x1016DR

Does anybody have such a shell case or a drawing in their collection? I would love to know the actual dimensions.

Answering my own question after getting 100's of pages beyond. They actually offer me the dimensions ;-).

100x818DR121
120x937DR145
150x1115DR182

I think at least Russia used the 120 and 150 mm. But I am not sure if they had 150 mm. Thought these were 152,4 mm (6 inch).

Actually I was thinking the same. This journal is not always accurate (to the level I want), and the overview does not show the actual shell case mouth diameter. I checked my reference list:

152x1116R182 Schneider-Canet --> could be the same shell case. But notice the difference in the rim style (R vs DR). I had a 1942 Finnish shell case in my former collection, I did note it as R-style as well. Maybe the rim was changed over time? Can owners of such a shell case check the rim style?

For the 12 cm I have nothing that comes close, always cool finding a drawing of a completely unknown shell case (to me).

In the same journal, but dated 1891, I find that besides the mentioned 10/12/15 cm L48 they also offer a 12 cm L40 and a 12/15 cm L45. No shell case dimensions given, but an image of a 12/15 cm L45 round clearly shows a shell case with a non-double-rim. I suspect this is the 152x1116R82. Especially since the article ends with a remark that the Russian navy adopted these guns.
