[manu1972]

hi guys, today I got this beautiful iron cross first class of the magnetic WWI. I am simply in a doubt as to the pin it looks like a K O, but as for the hitch the rent comes from the left side and the hinge seems to have another aspect could someone help me identify the manufacturer? and if this piece is good or not?
thank you all for your opinion
