Hello Daniel

Although the Stug III G was designed with a rotating commanders cupola not all Stug III G had them.

The main ball bearing factory was bombed mid production of the Stug III causing a major shortage of ball bearings thus many Stug III were built with fixed commanders cupola.

I do not have my reference at hand but the rule of thumb would indicate the same production shortfalls which befell the Stug III would have affected Stug IV production given they were build using the same parts and being built on a parallel time frame.

There is documented evidence from some vehicle restoration projects that turret rings on tanks had wooden spacers fitted between the ball bearings during the same production period due to a shortage of available ball bearings.

I hope this helps

What counts as mid production period for the StuG III Ausf. G? I want to build a late 1945-early 1945 StuG IV.

Daniel,

I'm in the final stages of a late StuG IV build myself and have archived and made available some info and building notes from my own project here:

http://www.ampscentralsouthcarolina.org ... _Demos.php

Look under Group-Build No. 1: DML StuG IV. There are seven pdf. files that constitute the nuts and bolts of a "build manual" to convert the DML early / initial production StuG IV into a late (but not final) production StuG IV. (The final production StuG IV's had the Pz IV J type hull extended tow eyes and the break covers without vents and with handles - information I only found when I was too late in my build.)

I also have a illustrated build blog here on Armorama:

http://www.armorama.com/modules.php?op= ... 904&page=1

Also, if you Google (or whatever search engine you use) the terms "Poznan StuG IV" you'll find plenty of links to the late StuG IV's recovered in Poland, one of which has now been restored to running order.

Here're a couple of happy snaps of my StuG IV late conversion:





I'm working on the figures right now, so no new posts in a while on the build blog, but hopefully something new soon!

Be glad to help with any questions if I can.

Happy modeling and Merry Christmas!

I'm sure the Stug III G started to have rotating cupolas fitted again in August/September 1944 until the end of the war so I would think the Stug IV was around the same time, they were initially stopped late 1943 around September/October, pre this date some early Stug III G were fitted with rotating cupolas which locked facing the rear of the vehicle (this was a production fault)and I'm not sure if it affected Stug IV production.

These come from the recovery of the "polish" STUG IV.



Looks to me like a bolted down cupola.

Hello Ray

The only thing I can definitely see from your photo is a damaged cupola.

The written reference I have which includes almost all the books published about the Stug III states more or less the information I stated above.

I will add, the History Facts books give a return to rotating cupola date as November 1944 for the Stug III, they also add there was never enough ball bearings to ensure all cupola fitted were rotating.

The books I have further state when the cupolas did not rotate they were welded.

Since I have never dismantled or constructed a Stug III I am at the mercy of those whom take the time and effort to research the subject and put their work in to print for which I am very thankful, I express this by buying the books.

My posts all relate to Stug III production, my point to Daniel was given both vehicles were produced at the same time from similar components it is reasonable to think they suffered the same production issues relating to the shared parts.

Maybe you have some further information you would like to share?

One of the biggest problems with this site is the misinterpretation of posts not helped in part by people not reading the posts correctly, this is further exacerbated by differing levels of intelligence, social discipline and manners.

Thank you for your photos I will study them and hopefully add to my understanding of the subject.

Hello Craig and thank you for another excellent photo although it is a little small.

I have all your books on the Panzer IV and understand you are not going to do anymore, is this true?

I thought you might produce another book about variants built on the Panzer IV; my main interest is the Brummbar (1st series modified and 2nd series) especially the roof.

Or given the photo posted the Stug IV for which there is a void of good information.

Am I right in seeing that the StuG IV in the factory only has three return rollers? If so I think it is the first time I have seen that on a StuG. It also has the spare wheels mounted in the forward position just as can be seen on those StuG IV wrecks in Hungary 1945. Much interesting, thanks for sharing.

Do you have a date for that photo?
