The interior of a 75 mm retractable turret model 1933 displayed in the museum of Fermont. Here the roof has been removed to allow the visitors to take a look in the turret. You can clearly see the two guns and the horizontal ammunition hoists. The large white plate is part of the ventilation system. This was necessary as the guns had a maximum rate of fire of 30 rounds per minute each. For more information take a look at www.maginot.info.
