Been like a kid in a candy store working here at Ras El Tin EN base for the last month. So much vintage Soviet armament everywhere you look...from 1950s vintage twin 23mm mounts through modern AK-230 30mm autocannon..and everything in between. They've also still got some Bofors twin-40 mounts afloat on patrol-sized craft.
They hauled an ancient patrol boat out for work a couple days ago and it has mounts that carry WWII vintage belt-fed MGs.. 1938 model DShK 12.7mm.
