The Pendulum mount seems to be the one you're after. It's marked KRUPP, after the company that produces the 12.8cm/61 Flak 40. Also, of course, the caliber length strongly indicates that it is the Flak 40.
This design is from 1942. A bit early for the 5.5cm, and of course is marked 5cm. It does make wonder, though, if this is supposed to be a navalized 5cm Flak 41. We'd need to very lengths and all of that.
HAHA! Success!
Yes, that would be the one.
"Bord" means "board" in German i believe (not native), so i assuming board implying the mounting platforms, many of these sketches are land mounting some sorts.
If I recall, the 3cm MK 103 was given "Bord" or "Bordkanone" mounts which were literally just wood and metal "mountings". There is an image or two online for these.
I suppose Bordkanone was used because the MK 103 is really a Luftwaffe airborne weapon first and foremost before a land mount. Flak was the primary word in use for land mountings so I suppose if you have Bordflak then you have a combination of a typically airborne cannon with a typical land mount (Flakvierling, Flak 38, and a piece of wood with some hollow steel supports I guess).

This details more thoroughly the oft-times unknown difference between Ftb 1941 and its successor, the 1941A. Additionally we get some of the thinking behind the swap to diesel motors.
MB507? Got it, thank you! I'll make the edits.
I think the 12.7cm Doppelflak is the most confusing. It can't come from the Pak 44 as the design year is 1940. I want to say it's related to the Flak 40 in development, but none of the lengths correlate. I think this is a unique gun.
Nice!
Recently I saw a sketch of the battleship H (RM25/15820), which mentioned 40,6cm C/34f.ALCON,
The Primary Documents folder for Germany has been updated and I've implemented a few new things here and there for you to look at. No doubt some things you will find interesting.
I'm interested to see where these plans will eventually end up.

If anyone can tell if there is a difference in caliber between the SK C/34f, g, and h, you get the golden cookie because I cannot figure it out.
P.S.: Will be moving a bunch of plans over from the RM 25 folder to their respective new homes as soon as possible. If you cannot find a ship plan, or want more, you're sure to find it in the RM 25 folder.
Please post whenever you find the time, I'll gladly add them.
I knew the 'h' was a bit bigger but I thought it might be production 42cm guns of some type. I don't recall the lengths at this moment but if memory serves roughly the length of 'h' guns divided by 420 does still equal about 52 caliber.Recently I saw a sketch of the battleship H (RM25/15820), which mentioned 40,6cm C/34f.View attachment 673901
I remember someone has measured the length of the barrel (including the breech) of the c/34f shown on RM 24/362 (fortunately the link is shown before
actually I started looking up on bundesarchiv after seeing that post), and I did the same and got the same results. It's about 21.1m, same as a 40.6cm/52, so I believe that to be 40.6cm.
RM 24/362, 363, 364, 366 shows the Drh LC/34 f, and 371 for g, 372 for h. The c/34h seems to be larger than the others, with a barrel over 22m in length like a 17in/52(my weird guess before without any reliability). The turret on RM 24/371 has a similar size as on 362 to 364, while the date on 371 is closer to that on 366, both July 1937. 362-364 is later, dated Sept. to Dec., and 371 even later in 1938. And then there's the similar three Drh LC/34 f4s and h4s, and the design of the quad turrets of two different sizes seemed to get optimized together. The dates between f and h were quite close of the three schemes.
This shows the development of Drh LC/34 h4 and f4 is almost identical, except that it's smaller in size.

I know nothing about the process of armament development though so I couldn't get more information from that

Maybe there's still a chance that the digital scans currently available that remains to be found (I wonder how to do that though). I remember that there are quite a few documents that are available on other sites like The Dreadnought Project but nowhere to be found on invenio. For example, below is a drawing of Prinz Eugen
Oh, I nearly forgot, I believe I actually have the latter two, but not the first. It should be in the RM 25 folder.
It can either be a longer 40.6 with a 55-caliber barrel, a 42cm with a 53-odd caliber barrel, or a 45cm/50-caliber of some sort.View attachment 673945Please post whenever you find the time, I'll gladly add them.

I measured the document provided by bundesarchiv (RM 24/373) and if there haven't been a mistake, I've got a result of 22437mm. And as I used MSPaint, if a limit error of 5px each time is introduced, it'll turn out to be (22.44±0.06)m. Here the 0.06m is the standard error while the limit is about 0.12m.
I'm still wonder if there was a plan for production 42cm guns, which has been the thought process behind why this might be a 42cm gun.
Oops, i was thinking if you have the twin turret version...
It appears you can contacts Invenio and requests copies of a document,scans (according to their translated guides), invenio said they wish to further expanding more digitalized scans in the future.
