Question about a german officers WWII belt

[H.Guderian]

Hello I've seen this belt with hook but I cannot identify if It's a german WWII period or not. I'm looking an original one to complete a SS officer's buckle. The hook don't seem to be in silver... Probaby a german police belt?
All help is appreciated
Thanks, George
