To keep the topic up and viewers up to date:

It is a lot of guessing but it seems to fit some how
I am pretty sure the crew didn't had a lot of space.

Yes I know but first I have to figure out how the canon was placed on the steel column .

Hello Wim,

maybe this two attachments will help you to make a 3D drawing of the gun fixation.

Hello
Here is a photo from inside a 10 cm Panzerkasematte.

Very nice Lars

Whow, things are getting better every time. Lars, thank you very much.

I do have a problem with the floor behind the canon and the way the cannon is moved backwards. So far I figured out it would have a double floor or a (work) floor and a lower part on which the carriage of the canon is rolling over.

From the info I have seen it looks that behind the canon there where two trapdoors. Moving up. But then, taking in account the available (lack of) space, you don't have much area to get the cannon backwards.

Great picture !

Do you know if it is in Hillersleben ?

Ok, here we go.
After some email for which I thank the senders, I made following drawing to make discussions easier.

What I am trying to figure out is how the yellow, pink and orange parts interact. The wheel in front of the pink part suggest that at least a part of the platform could be tilted (?) or it is part of the cable system which moved the cannon back and forth.

The things that puzzles me are the orange , pink and yellow parts.
Green part would be the double trap doors. The purple part at right would be the "hoist"for moving the cannon backwards and forwards.
The yellow part seems to be extra heavy constructed and moveable downwards.
The pink part left is fixed on the orange part and contains something that interacts with the carriage. But the green trapdoors don't llok to be strong enough to carry the weight of the cannon and carriage. Also once moved backwards it just fits inside and when you want to close the porthole it almost looks that the barrel is in the way.

So although the drawing looks detailed I can't make it "working". Any help or though are appreciated.

Hello Eax-E
The photo is dated October 1936. As far as I know it comes from the old Rheinmetall archives. Unfortunately no further information is known.

Hello,

Lars,
Ok, thanks.

Wimwe

Here is how I understand things :

Step 1 : The purple part is just an hold. It usefull to stop the the mobile part when it comes from it's "peace position".
Step 2 & following : Trappdors are open in order to move back the gun. The gun is pulled through cables (?).

Great work Arthur

The guntube had to be pulled up too.
As you can see when the carriage is in the backposition the kalotte can not be closed because the tube is in the way.
I believe that in the same way also the tube could be changed when the tube reached the end of it's life.

Good animated gif.

You placed the trapdoors higher. That was my first idea too. But I wasn't sure because the view shows "hinges" on the green track. Plus what about weight ? They made a massive steelconstruction under the firing position and no such construction in the back position ?

Hello,

My though was that by travelling the tube to the right the schartenverscluss could be closed. Agree ?

It's strongly hanged on the extremity to the rear steel plate but you're right.
