Hi all,

An image from Ebay. I think an 305mm Obuhov M1907 gun turret destroyed. Aegna island, Estonia ??

Hi all,

An image from Ebay. The weapon in question seems a 152mm ML-20 howitzer (or perhaps an 122mm M1937 gun) but, which is the purpose of the dials in the red circles ??
I have never seen this in these Soviet artillery pieces....

It is possible that this gun is used for test.
"the purpose of the dials in the red circles " is two pairs of pressure gauges indicating the pressure of liquid/air in the anti-rollback devices (rollback brake and knurler).
The upper pair of instruments (pressure gauges) shows the current value of the parameters.
The second pair of instruments (in place of the panorama / sight) to fix the values at the time of the shot.
It can be seen that both pairs of devices are connected to each other by litle pipes and wires.

Thank you, Yuri

It is most likely that the devices seen in the photograph are fire control receiving devices, similar to naval (coastal) systems of fire control devices. These devices provide centrally controlled firing at a sea target with uniformly selected pointing angles for all battery guns. Before World War II, the Soviet Union developed several varieties for towed artillery. Before the war, several 152-mm howitzers with such devices, designated ML-20M, entered service with the Soviet fleet.

The devices visible in the photograph are very similar to soviet device 23 (device receiving the azimuth at the guns) and device 44 (device receiving of elevation), which were used in coastal defense in the «Barricade» system of fire control devices.

Device 23 was mechanically connected to the lantern bypass of the coastal gun, and the rotation of the gun was fixed by a mechanical arrow, which had to be combined with an electric arrow that received a horizontal guidance angle from other devices.

In device 44, it was possible to introduce a correction for the inclination of the gun platform relative to the horizontal plane, as well as to calculate the change in the initial velocity of the projectile depending on the wear of the bore of the artillery barrel.

Yes, you're probably right.

152-mm ML-20M is a modification of the gun for the coastal artillery of the Navy. They were distinguished by changes in the shield, the presence of special receiving devices for vertical and horizontal guidance systems, etc.
An experimental series of three guns was made in 1940, but the tests of the guns were unsuccessful, and they were not accepted for service. The manufactured guns were sent to the front, where they were lost. After the war, the ML-20M index received guns that had undergone modernization.

Thanks, I didn't know! Very interesting! This, apparently, is one of these three experimental guns not adopted.

Thank you very much for your information, Statist...

Hi all,

Does somebody know where and when was taken this image of 300mm BM-31.12 rocket launchers ?

Soviet battery of naval guns 130/50 ("B-13"), installed on the Sabsky bridgehead (Luga line of defense) in early August 1941

Three guns near the village of Kerstovo.
Four cannons near the village of Yablunytsy.

The guns were placed on wooden foundations (logs tied with steel bolts). Around the embankment was made of soil, or of stones.

When the German troops launched an offensive in this area, the batteries had not yet had time to fully equip them with artillerymen. The Germans captured the battery in Yablunitsy. The Soviet sailors managed to evacuate the battery in Kerstovo, despite the strong battle nearby.

Photographs from 1942 show German military engineers dismantling and transporting guns from Yablunytsy.
