Krupp 42 cm Big Bertha
Permalink   


Hello everyone here on the forum. Please, what is your expert estimate of the combination of colors on Big Bertha,s 42 cm?

1, Base dark grey + yellow and brown spots

2, Base dark green + yelow and brown spots

3, Base grey green + yellow and brown spots.

I found a lot of variants from modellers - were there so many variants of cover - up? I have only got 3 historic photos for this type of cover - up. 

I thank very much for the answer. Ivo from Czech Republic. BERTHA IMAG1125 trim.jpgBERTHA1455834687.jpgBERTHA 1.jpg42cm_M_Gerat_24 BIG BERTHA PŘEDÁNO USA ARMY.jpg42cm_M_Gerat_25 DICKE BERTHA PŘEDANO US ARMY.jpg42cm_M_Gerat_18 big bertha fleky.jpg

Article says that base coat is Feldgrau, virtually 100% certain.
Now, as to what exact colour Feldgrau is!
Blotches are probably white, but maybe a yellow or a sand hue, with dark green or dark brown.
Take home message, whatever colours you use, somebody will say you're wrong.

The Takom Dicke Berta is very inaccurate - Steen Winther tried to figure out how to transform the Takom kit into

something more like the original but gave it up as too difficult. There are Hans van Oerle's .stl files on Landships II - these

are based on Steen Winther's 3D Solidworks model and are likely quite accurate. I don't know what scale you wanted for a Dicke Berta -

I think Hans' files are for a 1:72 model.

Thank you for the information on the Bertha issue. I looked for the color of the feldgrau and perhaps found an aproximate shade. 

Kit of Bertha is almost built,I can not make big adjustments - Iam just a average modeller... But I want to try minor repairs and replenishment according to the 3D model. IvoFELDGRAU.jpg

It looks like a large lever, to me.
However, it's not seen on any of the photos of "Big Bertha".

Hi Ivo,
I am pretty sure that the bar you are referring to is there to protect the carriage from damage during assembly and, in particular, to guide the barrel wagon when this is being driven up the ramps during insertion of the barrel in the cradle. The barrel wagon has what appears to be vertical rollers inside the wheels (look closely at the pictures you have uploaded) and the protrusions at the end of the brackets could help with holding the barrel wagon back when the barrel is being pulled off it?
Just a qualified guess after having studied this design for years
Cheers,
Steen Winther

Regarding the colours, I can direct your attention to a cannon outside the Australian War Museum, which is painted in similar colours and style to the 'late' Big Berthas. I have attached a poor picture, but you can find much better ones by searching for this gun: https://wikivisually.com/wiki/15_cm_Kanone_16

Where or from whom did you receive the metal barrel from? I have looked off on and on for one, but have yet to find one for purchase.

You're work is especially nice, thanks for posting!

looking at my own (poor) Takom kit, I notice that none of the handwheels actually looks like something working and I have some questions if anybody could help!

There are 3 handwheels on the kit :

The first in the front of the carriage but not connected to anything... Brake? Mooving the axle?
The second is on the right side of the carriage : elevation of the barrel? Brake?
The first is on the left side of the carriage just behind the shield : no connexion with anything and same question...

This model is especially disapointing on many other points but the way the designers consider the systems is one the worse side!

if any body can help...

In the Osprey book on the 42cm "Big Bertha", etc the authors (Romanych and Rupp) identify the handwheel on the left side of

carriage just in front of the breech as the "Fine Elevation Handwheel" - the crankhandle on the left side in front of the wheel is the

"Coarse Elevation Control".

The crankhandle on the right hand rear side of the breech is the breech block control - this was discussed in another thread on this forum.

Regards,

Charlie

Thank you very much for your answer!
If both wheels on the sides of the carriage are use for the gun elevation, any idea on the purpose of the one in the front of the carriage, just behind the frontal platform? My fisrt idea was it could be used to move the axle but I don't know if it was used on german guns as it was on french ones...

I don't know what the handwheel on the right hand side was for.

I think the handwheel on the axle may have been a brake - the 21cm Morser has an identical handwheel on the axle housing - the handwheel on the 21cm has

an inscription which, in part, reads "Bremse" or "Brake" in English. My guess is that the 42cm was the same.

Regards,

Charlie

It seems it makes sense, the point could be to found where base the breaks blocks located on the Bertha.
Thanks a lot for your help one more time!

The handwheel on the right side of the carriage is a puzzle. On Steen Winther's model it seems to drive a shaft

via a gearbox. The shaft runs forward to the right hand wheel.

Anyone have any idea what this was for?

Regards,

Charlie

I do believe that the handwheel on the right side of the carriage is a wheel brake. When the gun carriage was moved in a train, it had a soldier situated on a seat next to this wheel. I can't think of any other function during transport than a wheel brake....?

Very good observation, I agree with!
Thank you very much.

So only the purpose of the wheel on the front of the carriage is to be found.

I think the handwheel on the front axle of the 42cm was attached to a brake. The intent may have have been to have a brake

like the parking brake on a car to stop the wheels from moving. I found another image of the 21cm howitzer - the full inscription

on the brake handle is "Bremse.fest" or "Brake tight" according to Google translate.

Regards,

Charlie

Hello, everyone here. I´m also working on the back of the cannon. Please anyone know the purpose on this construction? Is it only used in transport configuration?bertha.jpgbertha foto 1,2.jpg

Thank you very much. Ivo from Czech Republic

I have attached another picture showing the carriage train in partial disassembly, attaching (or detaching?) the radgürteln (the linked blocks on the wheels). I believe that the brace you enquire about was there to prevent the tarpaulin from getting caught in the radgürteln during transport. It is not visible at any other stage of use of the weapon.

I also concur with Charlie that the front handwheel must be working on the same brake as the right side handwheel.
