Uh oh! OK. I looked up the sprues and that rear engine deck again...
I think that I was WRONG in my prior concerning those decks and the versions they would build to.
The Takom T55A, AM, and AMV kits all seem to share the same sprue "J" with the rear deck on it. And that deck does have the two rectangular rear-most grills and hatch-covers.... NOT what I thought it had!
And, as these Takom kits seem to have the original RUSSIAN-style rectangular grills, and NOT the "stepped" grills seen on the Czech tanks... It looks indeed like these 3 kits all would actually build the RUSSIAN-production hull (at least so far as rear hull decks go), and NOT either the Czech OR the Polish hulls. Sorry! NO Czech T55 direct from the Takom box, after all!
I have not looked at the Takom T55 AM2 kit yet.... Which has the box art purporting to be an East German (DDR) tank. IF that kit also "enjoys" the same sprue "J", it, too will actually build up as a RUSSIAN production hull, I think! Argh!
Takom T-55 frustration continues!
There IS some OK side to this, for at least some of us... The Russian tanks have been sold or given away widely across the planet, and so there are many possible minor armies and paint-schemes to consider.
Just looking on the brighter side!
