I can’t say for certainty without physically being able to inspect that piece unfortunately. I can make a guess though. I am a machinist by trade and in order to have counter bored holes, there must be material there to be machined out. You can see the socket bolts in the red circled areas. Alternatively you can machine out the inner structure for weight but I wouldn’t see the point in doing that as that adds to waste and machining time. Plus it wouldn’t serve as armor.
Compared to the upper turret plate, it visually matches in thickness. I’m guessing gaijin was able to measure that properly from the museum off the M1 so I would assume it’s correct. I don’t think the museum would have allowed them to remove anything so I can understand why it was not modeled in game correctly. I don’t know the correct shaped used based off the photos but using what Gaijin modeled for the Nera packs, I’d say that thickness may indeed be accurate.
The screws are fastened to that back piece that I thought wasn’t modeled in game. It is indeed a flat vertical surface so the backside of the nera backplate must also be flat.
That image is for the base M1. The armor for the gun shield on the base M1 would be different than the M1A1 and later for multiple reasons.
The Trunnion Rotor mount on the 105mm is a solid milled slab. And the the stabilizer elevation resolver is mounted in front of the Rotor, between it and the composite gun shield.
The Trunnion Rotor mount on the 120mm gun is cast and hollow on the rear side, but set at an angle. The Resolver is mounted behind the Trunnion Rotor bearing mount on the M1A1 and later 120mm gun Abram’s tanks.
Using the same image as you, there isnt anything between the nera and the trunnion, the only thing that could be missing from the model in game is the small 5 mm at best plate before of rotor, the rest is hollow.
That piece would no longer exist on the M1A1 and later, as it would no longer be necessary, as the Resolver wouldn’t be there anymore. To be honest, the M1A1 model in game was made well before this document was found.
Sorry for the crude drawing, but there are two pieces there not one
That’s a Sep v2 pictured.
I first though that piece you are speaking of was not modeled, @SPANISH_AVENGER pointed out to me it was. Im saying there is an additional piece of armor mounted to that which is not modeled in game. It sits there screwed into that piece. I don’t know what it’s called.
