Heyee I got this old tamiya t62 and i scratch build some components
with it i build a small custom storage box i plan to put it next to the commanders
hatch its quite big around 5cm*3cm. My question is were their any kinds of
customizations like this to soviet tanks at during that era?

I'm not sure. I have a couple of T-62 projects on going. A 1/35 Tamiya T-62A with Barrel Depot aluminum barrel and new Eduard PE set. I'm going to use Skif (or is it Techmod?) tracks for the kit. The other one I'm building is the Italeri reissue of the old 1/72 scale Esci T-62. With this one I'm using an old set of Eduard PE and an Armor aluminum barrel to replace the kit one I broke.

Neat. It looks kinda cool with it and adds allot of detail but i dont really know how historically correct it is, i also drilled several of the view holes in it to.
