Found this on Facebook...📸 Some journalists and officials visit an Italian artillery pitch equipped with an impressive 381 mm cannon.
🇦🇱 The site should be on the Albanian coast, after the country was occupied by Italians in 1915.
✅ Notice halfway through the fly the small (relatively) caliber used for shooting adjustment.
Could it be, the small, a 57 Hotchkiss, about 2,5 mt long. Useful shot about 1 km, 1,5 no: maximum shot 6 / 7 km, but no longer exploitable, for him. If well-collimated, he directed the shoot of the main piece. Both of naval origin. Keep in mind that the cost of the bullet was different: here is one of the reasons.
In my opinion it's the 381 Vickers installed in Brindisi in Cala Mater Domini before the construction of the batteries Brothers Flag and Brin, twin sisters of the Amalfi battery in Venice.
