Tank gunner's periscopes inconsistency

[Astulian]

“Jungle Fire” update added additional optical devices to many armored vehicles in game, notably periscopes for gunners.
In some tanks, like T-34 1941, gunner can use both while still being able to fully operate main gun, MG and turret:

Default scope

Periscope

Yet, many other vehicles doesn’t have this feature, for example T-34-85:

Default scope

Periscope - note how it's impossible to control tank weaponry

Here’s a list of vehicles with broken gunner periscope:
Valentine I
SU-76M
T-70
BT-7F F-32
IS-1
T-34-85 D-5T
T-34-85
T-34-85E
SU-85
IS-2
IS-2 44
SU-100
M13/40 (III)
M14/41
AB-41
Crusader
M8 Scott
M18
Churchill III

M4A2 (76) W @ Sherman II

• This two are weird - gunners can’t use periscope, like it doesn’t exist. This despite having gunner periscope visible on X-ray, like with other M4 variants with fully usable periscopes: Jumbo, M4A2, M4A1 76(W).

Sd.Kfz.234/2 Puma

• similarly doesn’t have periscope for gunner despite having it visible on X-ray:

Periscope is visible here

So what I’m wondering, is this an intended behavior? And, if so, why is this the case? All tanks seem to have gunner controls very close to periscope, it’s not like gunner changes seat to use it, why only on some tanks gunners can operate weaponry while using periscopes?

Dunno about the rest of what you wrote because I haven’t tested it myself, but IRL the Sherman’s gunner periscope does not rotate freely, but is slaved to the turret. The same might be true for the Puma Commander periscope, but I could be wrong about that, I will have to check.

Puma doesn’t have coupola so a fixed periscope as only way of looking outside seems not likely.
It would be weird even for german standards.

M4A1 76W in game, for example:

Gunner's optic with zoom

Gunner's periscope - it's not rotating by it's own, but tank weaponry & turret traverse are fully controllable

@LordBeaverbroke

Puma Commander

Puma in game have 2 crew in turret -
1st, to the right - “commander”
2nd, to the left “gunner”
Both have additional optics available to them, but they’re unusable right now:

Gunner's scope with zoom

Gunner's "periscope"

Commander's periscope 1

Commander's periscope 2

I like the option of having additional opticals (with less zoom than standard scopes) available to gunners. They have wider FoV, it’s easier to navigate around and engage at short range.
Yet, you can’t control weaponry on some vehicles while using gunner periscopes, and I wonder if anything could (or should) be done about it.

Yes, that is as it should be. the Sherman’s gunner sights were all fixed forwards and is fixed to looking towards the direction of the turret.

Still looking into the rest of what you said.

At least regarding T-34s:

Initially T-34 were equipped with two sets of optics: the periscopic and the telescopic one. Not exactly sure whats the difference between them was when it comes to their use, but they both could be used for aiming the cannon.

Starting from T-34-85, tanks came with only a single optical device intended for aiming the cannon, with the periscope being primarily intended for spatial awareness apparently.
