Turret loks like it has been found at garbage store where it has been stored at least 50 years. Just make a tini experiment. Get a steel pin (like a short piece of wire) warm it up on gas using a usual kitchen stove, then cool it into usual sunflow oil. You will find that it become to black color. It simpliest way to make a voron steel. Now try to remove voron layer up to white glowing steel. It wery wery hard to do. And it home-made voron steel. Now mean what needed to remove a factory-made voron layer. Really i has seen a submachine gun that has been produced at 1943, used by army during WWII and then sent to school where has been used for assembly and disassembly tranings until 2010. It has NO ANY voron layer damages. Also not protected parts of metal becomes to rust wery fast so turret can not have a " glowing methal on sharp edges". It just have no sharpen edges. Any edge have a fillet or chamfer on it to prevent personel damages, so it just have a some glows on edges. Also commander of any unit where turrets/whechies have similar painting damage not repaired, will be wery soon fired or even inprisoned.
