Here is a similar photo of other trucks with them on the flat bed.
A little bit off topic, but in addition to the previously posted Prototypes of the Pz.Sfl.II, the guns, 7,5 cm K.37 L/41 were also mounted on the Panzerzug 3. Which i assume to have now found 2 photos of.
An armored train infantry ambush event would be fun running round protecting the train or attacking it.

Now what the hell is that
Sd.Kfz.251 with what appears to be a Sockellafette.

At this point where are you even finding these lmao
All over. Ebay, Facebook other Forums.
Negativ, just look at the angled visor on the side.
As this thread is all-encompassing, I’ll post an American field mod, albeit one that has a German flair to it.
Now, in lower quality versions of this image, the guns are often mistaken as .50 cals. In this higher resolution photo however, we can clearly see that this is a German system, mounting two MG 151s with a potential third having been present before the mount was field modded.
This M5A1 Stuart was spotted in the towns of Sušice and Lnáře, apart of the U.S. 4th Armored Division that liberated the area in May of 1945. A number of other photos exist, and a caption from a local museum notes that the guns are of 20mm caliber.

Freedom also came from the West - Bohuslav Balcar | Books from Martinus (I think)
Lnář Castle was confiscated first by the Nazis, then by the Communists. They turned it into a training and recreation center | Central Bohemia

Looks great would be a awesome suggestion post.
Most likely there to mop up infantry then aircraft as Stuarts where more of a infantry support vehicle by that time. Not ideal but better then nothing a gun that size can still nock out a MG or sniper in a building.
Initial Durchbruchwagen D.W. The only 3 known photos. And the whole drawing.
(The 4th return roller was added later on after tests.)
Pretty cool vehicle wasn’t this is heavy pz4 thing
More like the beginning of the Tiger I line.
Could be a good 1.7 heavy assuming it doesn’t get a bunch of mid-war HEAT rounds, which is exactly the type of thing Gajin would do.
All early vehicles with the 75mm gets HEAT, so it would likely happen with this one as well.
