Be careful about using the reference links above for making a wartime T-34-76 (Great list BTW, Karl).
The Littlefield -76, though in great shape and well restored, was used well into the post-war years by Poland and as such saw a number of upgrades that basically brought it up to T-34-85 mechanical standards. On the interior this shows up as various fittings on the firewall, the inclusion of only six ready rounds as opposed to nine, as well as the mechanism for the engine fan/tranny louvers being moved back to the rear suspension tower on the driver's side.
Also, the transmission and engine photos are from T-34-85's and there are differences between these and "as produced" T-34-76's. The majority of -76's would have been fitted with the four speed transmission which, though similar, has a number visual differences with the later five speed. Also, it seems that many, if not most, would have been fitted with the "Pomon" engine air filter which sat on top of the engine as opposed to the "Cyclone" type which were located in the transmission bay (the references I have seem to disagree on the introduction date for the later air filters so this is my "best guess" given the information I have on hand).
