Thanks everyone!
Next is gun travel lock.
A lot of fiddling parts, but i managed to put it together and leave everything movable.
Here is lock assembled with secure hinge
Lock placed on it's marking
Down position when not in use
Up position when in use
Open lock
Fun fact: gun travel lock was added at the back since the gun overhang was 1.4 m, and the tank normally traveled with turret reversed.
The travel lock was offset to the left to prevent the driver's hatch been blocked by the radio box in the turret rear.
