It explains everything almost same as this form.
Let me add something:
It shot Flak 88mm shells, not the KWK 36 or KWK 43 ones, meaning it would likely have same penetration as Flak 37 4.0 BR in game.
2ndly It would sit around 5.7-6.3
3rdly It was later equipped with Zis-S-53, since at that time Soviets did not have any Flak 88mm shells to feed the custom made S-53 + 52-K gun.
It used it’s original Zis-S-53’s breech and they cut the barrel and welded 85mm 52-K barrel which worked.
The 52-K part in the video is not the most accurate assessment with the available information. There should be no 52-K gun parts (except the modified 85/88 muzzle brake) used in the conversion.
According to the Soviet Manual referenced by the Russian Wiki, the 52-K and D-5S/T have the same barrier length. The total barrel length of 52-K was only longer because of its muzzle brake. D-5S/T is shorter than S-53/Zis-S-53, but 52-K is longer than S-53/Zis-S-53.
Knowing that information, if the inserted gun-tube in the photo was indeed a 52-K gun tube. The T-34-88’s gun would only be longer than the T-34-85 3D model’s Zis-S-53 by the length of the muzzle brake.

However, as the image indicates, the T-34-88’s gun was longer by the length of the gun tube. That inserted gun tube is longer than that of the 52-K. Therefore, it can only be an 88 mm Flak 18 gun tube.
+1 Would love to see this. Would make for a good event vehicle.
Are you the same dude from reddit? No, the 8,8 cm Flak L/56 shells ARE THE SAME as the 8,8 cm KwK 36 L/56 shells, the only difference is the primer, being electric instead of striker. They fire the same shells and casings. Pzgr. Pzgr.39 Gr.39 HL, Pzgr.40 Pzgr.40(W), Sprgr. (different types) at the same perfromance.

Table Size Production.
Just awesone +1!!!
Honestly it would be so cool to see, taking into consideration that WT has had other vehicles with much more opaque history or just downright one of a kind prototypes.
A very well-done job. How long did it take you?
If this thing can shoot definetly not with Kwk or Flak ballistics without muzzle brake and recoil system that KwK or Flak has.
Less then I need to grind the German Ground Tech Tree
Thinking about it this would be cool as a squadron vehicle. I think it could be 6.3 and wasting this vehicle for an event or premium would be sad because it could at least narrow the gap from panthers to leopard 1 a bit.
Squadron vehicle means if people want it they can get it (and for a rank 4 vehicle rather easy or less time consuming) and it isnt in every game
The gun tube on T-34-88 was most likely a 88 mm Flak 18 gun tube.
It’s a bit hard to follow, is the final verdict that the photos are not good enough to prove SU-88 (update on post 1) or that more overlaying work disproves your original theory that the gun is not an Umgeseelt 8,8cm (update on post 2)?
In my previous attempt, I tried overlaying a frame from the newsreel with the WOT 3D model. However, that iteration was impossible, given that regardless of whether the D-5S gun tube was bored out or not, with a muzzle brake, it couldn’t possibly be the same length as the original D-5S. After taking a closer look at the overlay, the 3D model had been placed in front of the SU-85 gun shield. Using the hitbox model as a reference, I adjusted the 3D model to properly overlay on the gun shield.
A more accurate overlay should be something like the following:


I see now, especially with the difference between your first overlay and this current one.
Features of the gun appeared to resemble a 85/88 conversion, your original overlay conflicted with this theory and you started to disprove it before better overlay work showed that this gun is definitely modified somehow.
Excellent work, always amazed to see discoveries like this, 80 years on.
Side note: I keep seeing skeptics suggest 85mm KS-1 could be the reason for the “step” in the barrel, but does not explain the muzzle. It’s a harder gun to find info on from cursory searching, but may be worth adding to your barrel length comparisons.
So much has been lost to history, even in the last 100 years and it’s a shame. At least you managed to dig this gem up so congrats.
+1 as an event or premium
KS-1 was not officially installed on SU-85. The normal D-5S should always look that way. However, the guns on different SU-85s looked like one way or another, depending on which photos you look at. There may be an information gap in the SU-85 variant.
Quick update on the SU-88 and the T-34-88. According to “Documents of the Quartermaster General of Army Group Courland: Organizational charts of the Army Group’s supply units and the subordinate AOK (General Local Health Insurance Fund) and associations, etc. ”, 85 mm ammunition was not in any German unit or stockpile inventory . It is very likely that the Germans in Courland did not even use any captured Soviet 85 mm AA guns in their original configuration.
Given that, replacing the guns on SU-88 and T-34-88 with the captured 85 mm 52-K gun would be more logistically improbable than replacing them with 88 mm guns.
This is awesome, what a wild modification. Would make a great event or premium vehicle +1
Russia gets a near fictional stabilizer t-34 as a TT vehicle, we get an apparently very much real and videoed t-34 88mm as a TT vehicle.
It‘s a fair deal
