This is a "relaxation" project, built out of the box with only a few minor additions and changes (like a few handles, replaced antenna and few more).
I cannot recommend this kit high enough - do not know enough superlatives. For the price of a couple (or a bit more) of pints one can get what is probably the best 1/72 tank kit ever.
As it was a quick build, I did not go into too much detail and research (a few articles and a few photos for reference) - just enjoyed the build.
