Bronze Panzer Badge 1957

[Philips]

Hello!
Please look on this badge and please write me - it's late or middle version 1957 badge. I'm think it's not early 1957 badge - I'm have early panzer badge (silver and bronze) in my collection.
So - middle or late?

I think this is a early/mid 70s piece.

It,s quite a rough one i,d say mid-late probably a late one .
