The kit include these items:

• 90mm AA turret

• 152mm turret
• 381mm turret n1

The models were created based on blueprints, photos and historical documentation. They were created with precision in detail and in real units of measurement to be a faithful reproduction of the original.

The STL files are in 1:200 scale (in mm units).

N.B. There are tiny parts, a resin printer is highly recommended.

For any difficult or question I am always available to give you assistance.

I would be very grateful if any of my models could help you to do a great job.
