In some ways this is an excellent model: finely detailed parts for the advanced modeler. Case in point: the model has a metal sprue with what I believe is a cover plate for a roof periscope(?) and lift hooks, etc. The hokks were just too smal for my craftmanship level. The same goes for the 'too-many track links, 3 per track set But I add that a skilled modeler will likely love this part. The only other surprise was the fighting compartment roof - I did not know the Soviets made such. This was not apparent in the box art. I have since ordered what I believe to be the more-common open-toped version from this same producer.
