The grain in the pictures is actually in the document the scans came from.
The text states the following about the kit:
*The low clearance chassis has been replicated down to the finest detail, even the cast iron surface has been faithfully recreated.
*The characteristic half-sphere turret and powerful 100mm cannon are faithfully reproduced
*Not a detail has been spared, even with finer parts such as the engine grill and cast iron wheels
*Kit #35257 Overall length: 259mm Overall width: 93.8mm
*In addition to the T-55A with enhanced deflection capabilities, the DShK-M with anti-aircraft armament can be selected as well.(not sure what that meant)
*This kit also lets you assemble the T-55A as it was produced in Czechoslovakia and Poland. Comes with 1 tank commander figure and decals for 5 different tanks.
