I bring to your attention an overview of photo-etched images for the JS-4 tank model from Trumpeter, namely the 05573 Soviet JS-4 Heavy Tank. An exhaustive review of the model itself with comments from DmitryShavrin can be viewed on the Panzer35. The assembly instructions (the only thing missing in the review, in my opinion) can be downloaded from Scalemates.
These kits are manufactured by VoyagerModel:
PE35707 Russian JS-4 (Object 245) Heavy Tank Basic (For TRUMPETER 05573),
PE35708 Russian JS-4 (Object 245) Heavy Tank Fenders (For TRUMPETER 05573)
and E.T. Model:
E35-216 Soviet JS-4 Heavy Tank For TRUMPETER 05573.
And although VoyagerModel has two kits, they are positioned by the manufacturer as a single kit, which can be clearly seen on their website.
PE35707 is packed in a standard branded box
which contains three frames of yellow metal of approximately the same thickness (I give etching scans at 1200dpi on both sides)
and one of white metal, much thinner than its sisters (it’s scary to take it straight into your hands)
Noteworthy is the turnover of Frame B – I wonder if this notch will help to bend the plate evenly (round)?
Plus there is a metal barrel of a coaxial machine gun (probably?), A type and location different from DShK, a piece of wire and two plastic rods and 12 very small (1.5 mm long) metal bolts that are used to attach spare tracks (the entire listed range shown on the back of the box).

PE35708 would not fit into the box, so the packaging is different, but also branded (it was worn out, so without a scan). The set contains only one yellow metal board, but healthy (233 mm).
Plus instructions on 3 A4 pages.
The competitor has no less branded packaging,
and a separate frame for DShK
The grille frame is not as thin as the VoyagerModel, but significantly thinner than the others. Tanks with an internal notch are also interesting here. Is this a new trend now, or are these competitors the same company?
