It could be OK but it's hard to tell without good close up photo's. It's difficult to see any details. I would like a close up of the wreath (the ring around the Swastika) as it looks a bit strange.
No, It's a polish fake.
I know you know your stuff Sid Too me the detail or lack of it on the wreath made me cautious.
and where's the ritter kreuz.
It comes from polish version of ebay called "allegro".I saw this auction yesterday and I already knew it was a fake...This seller had also crappy SS skull for sale. It also looks like a ground dug,I think he keeps fakes in bad conditions on purpose to make them look more "genuine".
Here are some pictures of this "original skull":
The TK is bad for sure , even it's condition can't hide that - a sneaky seller to be avoided ..
