Hello Everyone,
Unfortunately i do not speak russian, but i have some information to help you.
My name is Francis Pulham, and i own some of the photographs shared, i also wrote the articles on
http://www.tanks-encyclopedia.com/.
I see that my photographs have been discussed here, and i can help you a little.
After a lit of research, i found and purchased two photographs of what i believe to be T-34s with 57mm guns.
It is now agreed with myself, and other historians (including Yuri Pasholok) that this is indeed a 57mm gun tank.
Not only this, i think i have found who the commander is, and found another photograph of this tank.
this tank is also this tank:
The explanation is this: On the 17th of October 1941, the 21st tank brigade attacked the Germans who were positioned along the Volokolamansk highway in two groups, and along the Turginovskoye highway in a third group.
The first group was numbered "1" to likely "8", however only numbers "1", "4" and "6" have been found. "1" was commanded by Hero of the Soviet Union Captain Mikhail Pavlovich Agibalov. They were advancing west towards the Volokolamansk highway, and reached the village of Emelyantsevo. One tank was hit my an anti tank gun and blew up. This was tank number "2" commanded by Lieutenant Sergey Mikhailovich Kireev.
It is strongly believed that this tank is number "2", commanded by Kireev and lost in Emelyantsevo. The anti tank gun was engaged and destroyed by S.Kh. Gorobets.
For everyones interest, i also own the only known picture of "1", commanded by Captain Mikhail Pavlovich Agibalov:
You can clearly see the "1" on the hull side. he was killed by the village of Naprudnoe:
The location of Captain Mikhail Pavlovich Agibalov's tankI hope that this has been useful, my work on the 21st tank brigade continues, and i am working closely with "Максим Фоменко", who wrote a good book on Kalinin during the war.
In my collection of photographs, i have tanks number "4", "6", "21" and "24", plus the suspected "2".
I all willing to answer questions as well.
