We can see few tanks that have same features in the same period (after snow season, in heavy mud season). Features of these tanks are the following.
· With 1940 type disk road wheel. No narrow disk wheel. (It can't be in №112 and STZ.)
· With a headlight. (It can't be in №183.)
· With early "V" pattern tracks. (It can't be in №112 and STZ.)
· The hull machine gun mount ring is turn-"U" shape. (It can't be in №183, №112 and STZ.)
· With a jack base on the right side hull rear. (It can't be in №183 and STZ.)
· Rear towing devices are shape of "J". (It can't be in STZ.)
· A folding line of the front fender is sharp edged. (It can't be in №112.)
· The turret is a simplified welded shell model 1941. (It can't be in №112.)
· The top hatch has a round bulge to the left. (It can't be in №112.)
Therefore, these tanks can't be in №183, №112 and STZ. In these tanks, an important point is the track. It is the same type as №183 tanks' track just after the evacuation to Nizhny Tagil. Just after the evacuation to Nizhny Tagil, №183 factory could not product many of parts of T-34. Many parts were supplied from UZTM. I think that not only some parts but also some tanks were producted in UZTM until production in №183 went well. There is nothing fot it but to say this.
砲塔 Turret;
・溶接製砲塔のみ。1941年簡易型溶接シェルで後面パネルのボルトは8個。駐退機カバーのボルトも含めすべて六角の平頭ボルトだが、他工場のものより小さめで、一見は従来型円錐形ボルトに見える。
・ペリスコープは左側にPT-4-7型1基だけのものと、左右2基のものがある。
・ハッチ上面の膨らみ方は左側が大きく膨らんだもの。視察装置跡の穴は最初からないもの。
· Welded turret only. Simplified welded turret shell model 1941 with a wide rear panel with 8 flat hexagonal bolts. All bolts on the gun mantlet and on the rear panel are flat hexagonal bolts. But the bolts are smaller than ones of other factories. Therefore, at a grance, the bolts look like conical bolts.
· The periscope is only one left, PT-4-7 type. Few tanks have two PT-4-7 periscopes.
· The top hatch has a round bulge to the left.
· The driver's hatch is a new type. It is attached to the front panel that was designed for the old hatch. Standardly, the base of a right periscope was remained.
· There is a left headlight.
· There is an antenna post on the right hull side.
· There are metal fittings for five external fuel boxes (flat setting type) in the early model. Three sets are on the left side, and two sets of them are on the right side. In the late model, all metal fittings for external fuel box were discontinued.
· There is a jack base box on the right side rear.
· Tools on the right fender are three sets of five grousers, a tool box and extra tracks.
· Tools on the left fender are a lower large box (for a gun barrel cleaner) and extra tracks. There aren't two "U" shackles nor metal fittings for grousers.
· Front fenders are simple and standard length. Folding line between horizonal part and vertical part has sharp edged as STZ. There is a line on the outside of each fender. Front outside edge is rounded.
· All bolts on the rear panel including the exhaust pipe cover are flat hexagonal. The bolts are smaller than ones of other factories. Therefore at a grance, the bolts looks like conical bolts.
· Front towing devices are shape of "γ". They are riveted and welded. Rear towing devices are shape of "J". They are riveted and welded.
· The front edge are riveted.
· A mount ring of a hull machine gun is a horseshoe-shaped. But the welded line of the armour was interrupted in the centre.
· A tiny handrail is on the rear transmission hatch. No keyhole.
· Metal fittings for shovels are nowhere.
足回り Undercarriage;
・履帯は狭軌500mm幅の、V字模様の初期型。

・誘導輪はゴム縁のある1940年型。
・転輪はプレス式1940年型。
