Russian WWII 76.2 mm Cannon Ammunition

Thanks a lot for your reply!
Too bad you don`t have any other examples with this kind of markings!
My suspicion is that this shell in particular was, at one point, refurbished by the Romanians and then again refurbished by the Germans (by applying the German markings over the Romanian paint). I will elaborate below.
According to D435/2b "Die Munition der Beutegeschütze und Werfer" from 1943, German markings for captured ammo did not change the paint and used exactly what the Russians were using - meaning either unpainted and greased shells, or light gray coloured. This color scheme is exactly what the Russians were using and it is confirmed by Russian manual drawings. Of course, the new German designation for the round had to be marked - in your case it is 7,62cm Sprgr. Patr. 284 (r) - Which is the UOF-354M round using the OF-350 shell for the 1902/30 field gun.
On another note, from the photos you posted it seems to me that your shell is painted yellow with black markings. As per the above, this does not correspond to either German or Russian markings. In the Romanian artillery coding for markings and painting, HE shells are painted yellow (shades vary from pale yellow to bright yellow depending on stocks, relic preservation in the ground, etc.) and usually have the painted markings in black using a specific sequence that goes
On top of that, from archival data regarding some test firing we know that there was a 76,2mm HE shell captured from the Russians designated “No.12” , and although we don`t know exactly what model it was, considering all of the above I think we can conclude that No.12 is the OF-250 and that your shell is marked according to the Romanian marking codes.
Your shell seems to break the rule a bit by having the lot and year numbers on two different rows rather than being on the same row. Other than that, all other elements fit. Also, please check if you can read anything else on the fourth row. It should read something like
TC-76[SUP]2[/SUP]-Nr. XX, where XX should be in the 22-29 range.
I know this is maybe complicated to follow, but I hope you understand my point.

Tank archives has published the translation of the document introducing the BP-353A as part of the ammunition loadouts for the M1927 Regimental guns (dated October of 1942).

So I will be displaying my BP-353A in a 76x385 case but will have to add the black stripe. Can someone tell me the width of the stripe and how far from the top it should start?

For those interested in the previously mentioned and rather weird 53-BR-350A (53-БР-350А), BR-350A (БР-350А) for short, projectile there's a series of numerically simulated impacts of it on armour.

As far as I can tell it the person uses finite element analysis (FEA) for the simulations, but the grid (mesh) size is pretty coarse, so don't expect really high fidelity/accuracy.
There are some other interesting impact simulations, which can be seen by visiting their main YouTube channel.

Czech document says that the stripe is positioned on the cylindrical part of the case (neck).
Attached pic shows the UBP-353M it looks that the bottom of the stripe lies at the very bottom of the neck.
As for width, I have not exact data, but I would use the Eyeball Mk.1 to measure it
