Ну а потом после начала семидесятых бац, и тексты Мелконова и Ткаченко. И хоть кол на голове теши.

Первоначально было изготовлено восемь таких установок для Кронштадтской крепости: четыре для форта Алексеевский (Красная Горка) и четыре для форта Николаевский (Ино). За большую высоту и характерные очертания русские артиллеристы называли 305/52 открытые артустановки "журавлями".

There has been talk on the forum about 302/52 open carriage guns. I am most interested in the 4 "cranes " or "журавль" that were in Ino. I have been there many times. Ino's guns are clearly different from, for example, Krasnaya Gorka's guns because Ino's guns had a strange external ammunition crane, perhaps this "журавль", which is not seen in other guns than the Polygon cannon in St. Petersburg. Durlacher's carriage was electrically and pneumatically operated and had an automatic loader and a gun elevator into which a projectile and two powder charges could be placed. The ammunition feed opening was on the right side of the gun and the powder charges (2 x ½) feed opening was on the left behind in a separate armored space.
On Krasnaya Gorka, the elevator and the transfer of the projectile were done manually with cams on both sides of the gun. This is also clearly visible in Gorka's pictures.
On Ino, the situation was different, but still hand manual hand work. The projectile was brought to the right side of the carriage and an external hand-operated crane (lifeboat-style)"журавль", lifted the projectile in front of the lock. The lock and loader were also hand-operated. However, the strangest crane was the external lift for the powder charges, which was in the rear of the carriage. The pictures shows a metal torpedo into which the powder charges were placed and which were then lifted manually up to the carriage's upper deck and further onto the lock. This was the only way to do it in Ino.
So it is no wonder that the carriage, which was already wobbly in any case, was named crane "журавль". Overall, the carriage was slow, unstable and poor and was soon replaced by a new carriage, which was delivered to Estonia and Örö, and would also have been delivered to Helsinki. However, history turned out differently.
