Russian Mine clearing tanks

[DRG]

Here's a little research project for those of you with the resources to ferret out info like this ( you know who you are....... )

This website--------- http://www.wio.ru/tank/tank-tral.htm

has some lovely photos of various Russian tanks with the PT-3 mine rollers attached


This website http://en.wikipedia.org/wiki/Mine_roller ( yes....wiki ) says.......

"Prototypes were tested based on the T-28 medium tank in 1940. Development was interrupted by the start of World War II, but resumed in 1942. T-60 and KV tank chassis underwent trials, but only the T-34 was deemed to have a sufficiently robust transmission and clutch

That explains the T-28 photo. Its a test prototype that never saw action we can ignore but the KV-1 photo is reportedly taken in Karelia which is a long way to ship a prototype if you don't want to actually test it under battle conditions

So the first question is........... how many KV-1's were field tested with PT-3 mine rollers attached and did any actually see battle.

The second question is how far did the IJ-2 experiments go.
