Yup, that would be it. Silly me skipped straight to the AMV in the fisrt post.
Thank you!
BA-10M suggestion is finally done. Up-armored T-26 is still pending.

Want, unfortunately it may be a one off type vehicle but im hoping its not
Not that being a one-off matter much to me, and besides, we don’t even know what it is in the first place lol

Muzzle brake too, I’m just not sure what’s going on here,
Could it be a single gun of the ZSU-57-2 (ZSU-57)? Any idea when the photo was taken?
That’s SA-kuva number 147533.
“Sotilaiden takana kuorma-auton lavalla oleva tykki on 57 mm:n 48 kaliiperin merikanuuna mallia Nordenfelt (57/48 No).”
Behind there is another gun on something. It doesn’t look like that one can be operated with what ever it’s mounted on.

Great info, thanks!
The mount the second gun sits on looks the same based on the handwheel seen at the back of both of them, but without any armor on the front.
Edit: Seems like it’s a 57mm Nordenfeldt gun. Same armor plate.

Good find
All we need to find what truck chassis is mounted on
As well as the shell it uses
The truck shouldn’t be too hard to find I reckon, but the data on the ammunition might be a bit harder, though. According to Jagerplatoon it had APHE, SAPHE, HE, Shrapnel and Canister Shot. I only have some data on two Swedish projectiles used for the 57mm L/48 Marinkanon m/89, which was made by Maxim-Nordenfeldt/Finspång Bruk and seems to be the same or copy that Finland used.
So theirs should be similar or the same I feel as that was pretty standard early in the century. I don’t know what ammunition they may have produced later on, however. So take it with a grain of salt.
Design illustrations of shells
Design of the HE/SAP (note that it uses a base fuze). Name: Vanlig Granat/Common Shell.
Shell Weight: 2 575.75 grams (2.575 kg), ±25.92g.
Explosive Weight: 78.08 grams
Fuze Tube: 67.715 grams
Total Projectile Weight: 2 721.55 grams, ±27.22g.

The other drawing I found show two shells, one being simply “Granat” which basically just means “Shell”, and the other one is more interestingly an anti-armor shell, “Pansargranat”.
The drawing only has one table of data, so I’m unsure if both had similar weights with just slightly different dimensions, or if it’s just data on one shell but not the other. Nevertheless, these are the weights for the parts given (converted to grams):
Shell (empty): 2 429 grams (2.429 kg).
Explosive Filler: 90 grams
Bottom Screw (plug): 85 grams
Driving Band: 48 grams
Percussion Tube (fuze): 70 grams
Complete Shell (projectile): 2 722 grams (2.722 kg)

So, both designs are very similar to eachother, but on the second one the explosive weight is increased slightly with basically identical projectile weight (0.45 grams difference). The muzzle velocity is likely the common one on the gun of 540 m/s (not to be confused with 704 m/s which is only for the B-version with an L/55 barrel).

The poster on Twitter mentioned indigenous APDS developments, and even a prototype L/68 barrel for the 100mm. He claims that they can be found in a publication of a Finnish armor magazine.

Oh my goodness… We need to find a copy of that magazine ASAP. I really want this in the game.

Hey all, fresh of the presses comes Bofors new anti drone system:
Would be an absolutely amazing addition to high-mid tier and become what the VEAK used to be :)

They also talk about a book, which mentions StuG’s Finnish made APDS round. It gives whopping 200mm at 1000m.

Here’s a rare picture I found of the modernized Finnish ZSU-57-2, which was known as the ZSU-57-2M. For a bit of history these vehicles were an attempt from the FDF to increase the lifespan of the aging ZSU-57-2’s in the 1990s. The original plan was to upgrade the whole fleet of ZSU’s, but after the upgrade costs proved too expensive the project was canned after only a few vehicles were upgraded. The upgrade included a radar (which can be seen in the photo) as well as configurable ammunition (HE-VT) among other smaller upgrades such as electronic calculators and better sighting systems.
As for the caption it reads: “A modernized ZSU-57-2M vehicle Ps 462-4 photographed at the Armored Brigade. The picture shows for example a new angular part that was added to the back of the turret in the modernization. This part housed a lot of the modern components which were responsible for hardware managment.”
The picture and some parts of the text were sourced from the Finnish armor guild’s magazine. Regretfully it didn’t really give any new info on the ZSU-57-2M, but at the very least we got a new clearer picture of the vehicle.

This is excellent! Do you own any of the source magazines or was this found on the internet?
Where did the HE-VT shell come from? Would they have bought it from Chinese? I can’t remember if they were also made in Eastern Europe for the towed guns.
I’ve own only a couple of the newest numbers physically. But on the armor guild’s website they have an archive of old issues. I actually managed to find the number that had the article about the T-54, unfortunately it wasn’t available to be read.
As you can see the same picture of the T-54 is used here, so this is unmistakenly the right issue. I’ll try to get my hands on this magazine, but no promises.
