It could be Zevezda (sp?) they have a 1/100th range, though there is quite a lot of parts for one of their kits.
yes a few things wrong with this suggestion.
1) it is odd there are no tools/track links/stuff moulded down the hull sides ?
2) turret has large hole & ring not a peg.
3) hull bottom does not have lips moulded to the sides to go over the tracks.
4) tracks appear to be a single moulding of track & sprockets & return idler with outer road wheels added afterwards
Also one of the rear engine fans has a raised box around it.
