Russian Railway Gun ID

[Investigationehistoria]

Hi everyone

I'm new to this subject but completely engrossed in it. I was just watching some military videos and the video below was recommended. They don't give any information out about the gun it's self just that they are near St Petersburg. I cant believe the size of it. I have tried to research what it is myself and think it is a TM-3-12. Though as I say my knowledge is limited and there appears to be parts missing, when comparing it to online images.

Any help appreciated

Video shows two big cannons ATM-1-180 and a TM-3-12 conserved in Krasnaya Gorka fort, the first 180 mm, and 305 mm the second
Two examples of TM-3-12 are preserved today, one in Moscow, and other in a Railway Station of Ukranie

I cant believe the size of it

Compared with the Yamato's naval cannons ( 460 mm ) they are small
