The Su-76M simple construction made it the most produced Soviet Self-propelled gun of World War II,(and second most produced soviet armored vehicle overall, only after the T-34 tank).
The kit can also be of very simple construction, nonetheless the parts are very well moulded, with very nice details like the small photo-etched fret and especially the interior details are good with nice ammunition for the 76mm gun. Since the superstructure has an open-top, there is a complete interior for the fighting compartment.
The tracks are made of plastic, and are ok.
Decals are provided for 4 overall green vehicles.
The instructions are ok, but you'll need to check some details with images in the internet (if you want an accurate kit).
The cons: There are some sink marks, most notably on both sides of the gun mantlet. And most of the PE parts are not to be used in this model.
Overall: its an excellent kit with no competition in the 1-72 scale.
